In the Christian Bible, the Old Testament books are arranged so that this verse is the last verse in the Old Testament, emphasizing the Christian interpretation of this passage as a prophecy which is fulfilled in the gospels immediately following. In the Jewish arrangement of the scriptures, Malachi is the last of the minor prophets, and is followed by the books called "Writings"; thus it is nowhere near the end of the Hebrew scriptures. For more problems with this passage, see below. The fame of Elijah rested not only on his great life and the Malachi prophecy, but on the fact that he did not die; he was carried into heaven without tasting death II Kings 2:

Suppose that each number in the table is divided by 7 to produced a quotient and a remainder. What is the same about the results of the division in each row? Common multiples and the LCM An important way to compare two numbers is to compare their lists of multiples.

Let us write out the first few multiples of 4, and the first few multiples of 6, and compare the two lists.

The numbers that occur on both lists have been circled, and are called common multiples. The common multiples of 6 and 8 are 0, 12, 24, 36, 48,… Apart from zero, which is a common multiple of any two numbers, the lowest common multiple of 4 and 6 is These same procedures can be done with any set of two or more non-zero whole numbers.

A common multiple of two or more nonzero whole numbers is a whole number that a multiple of all of them. The lowest common multiple or LCM of two or more whole numbers is the smallest of their common multiples, apart from zero. Hence write out the first few common multiples of 12 and 16, and state their lowest common multiple.

Hence write down the LCM of 12, 16 and 24? Solution a The multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96,,… The multiples of 16 are 16, 32, 48, 64, 80, 96,,… Hence the common multiples of 12 and 16 are 48, 96, ,… and their LCM is Two or more nonzero numbers always have a common multiple — just multiply the numbers together.

But the product of the numbers is not necessarily their lowest common multiple. What is the general situation illustrated here? Solution The LCM of 9 and 10 is their product The common multiples are the multiples of the LCM You will have noticed that the list of common multiples of 4 and 6 is actually a list of multiples of their LCM Similarly, the list of common multiples of 12 and 16 is a list of the multiples of their LCM This is a general result, which in Year 7 is best demonstrated by examples.

In an exercise at the end of the module, Primes and Prime Factorisationhowever, we have indicated how to prove the result using prime factorisation. This can be restated in terms of the multiples of the previous section: On the other hand, zero is the only multiple of zero, so zero is a factor of no numbers except zero.

These rather odd remarks are better left unsaid, unless students insist. They should certainly not become a distraction from the nonzero whole numbers that we want to discuss. The product of two nonzero whole numbers is always greater than or equal to each factor in the product.

Hence the factors of a nonzero number like 12 are all less than or equal to Thus whereas a positive whole number has infinitely many multiples, it has only finitely many factors. The long way to find all the factors of 12 is to test systematically all the whole numbers less than 12 to see whether or not they go into 12 without remainder.

The list of factors of 12 is 1, 2, 3, 4, 6 and It is very easy to overlook factors by this method, however. A far more efficient way, is to look for pairs of factors whose product is David Richard Berkowitz (born Richard David Falco, June 1, ), known also as the Son of Sam and the Caliber Killer, is an American serial killer who pleaded guilty to eight separate shooting attacks that began in New York City during the summer of The crimes were perpetrated with a caliber Bulldog ashio-midori.com killed six people and wounded seven others by July List of composite numbers between 20 and The list of composite numbers between 20 and 40 will help you to find the factors of a number.

C programming source code to display all prime numbers between two integers entered 20 50 Prime numbers between 20 and 50 are: 23 29 31 37 41 43 In this program, the while loop is iterated (high - low - 1) times. In each iteration, whether low is a prime number or not is checked and the value of low is incremented by 1 until low is.

Composite numbers are those which have #3# or more factors. Prime numbers are those which have exactly #2# factors. There are more composite numbers than prime numbers, (can you explain why this is so?) So it will be easier to count the prime numbers and subtract them. The GCF is the largest shared factor(s) between 2 or more expressions Steps to find the GCF: 1.

Write the prime factorization 2. Circle (use) the lowest power of the common factors (look at the bases). 30 is a 7-smooth number (aka highly composite number or humble number) in that its prime divisors are all ≤ 7.

30 is an smooth number in that its prime divisors are all ≤ 30 is the product of the first 5 nonzero Fibonacci numbers (F 1, , F 5), thus: 1∗1∗2∗3∗5 =
