For example, in number 6, we can
find 2 factors: 2 and 3, because 2 times 3 is 6. And we can also say that 6 is
a multiple of 2, and a multiple of 3.
Factoring is the process of finding
the factors. For example, to find the factors of number 54, we divide it by 9
and we get 6, then we divide 9 by 3 to get 3, and divide 6 by 3 to get 2. So we
find that numbers 9, 6, 3, and 2 are all factors of 54.
A Prime number can be divided evenly
only by 1 or itself. And it must be a whole number greater than 1.
Prime Factorization is the process
of finding all the prime factors of an integer. Here is a simple way. In the
first diagram below, the prime factors of integer 891 is identified to be 3, 3,
3, 3, and 11.
