Factors of 40

If a number does not have a factor besides 1 and itself, it is called prime. Example: 5 have no factors, whole numbers that can be divided by evenly, besides 1 and 5. It is therefore prime.20, and the other hand, the factors 1, 2, 4, 5, 10 and 20. Because it's factors besides 1 and itself (2, 4, 5 and 10), it is not prime.

In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly, without leaving a remainder.

Factor

Define factor:

Let us start by defining "factor", the word on the extreme right of the term "highest common factor". From out of plenty of meanings of the word one specific meaning is used here. They say that number x is a factor of number y, if they can find another number k such that y = k x. Alternatively, they can also say that on dividing y by x (y as dividend and x as quotient) they get a remainder of zero.

Ex:1 (Factors of 4)
Factors of 4 are: 1, 2, 4
Ex:2 (Factors of 12)
Factors of 12 are: 1, 2, 3, 4, 6, 12
Notice that 1 and the number itself will always be among the factors of a number. It is natural, because for any number x, they have x = 1 * x and also x = x * 1.
