Answer:
The factors of a whole number are the whole numbers which
divide into it exactly.
For
example, the factors of 18 are 1, 2, 3, 6, 9 and 18.
A prime number has only two factors, 1 and the number itself.
For example, the factors of prime number 7 are 1 and 7, the
factors of the prime number 19 are 1 and 19, the factors of
prime number 23 are 1 and 23.
