Answer 1

Answer:

The numbers which exactly divides the given number are called the Factors of that number.

Factors

As we can see that we get the number 12 by

1 × 12, 2 × 6, 3 × 4, 4 × 3, 6 × 2 and 12 ×1

Hence,

1, 2, 3, 4, 6 and 12 are the factors of 12.

The factors are always less than or equal to the given number.

Multiples

If we say that 4 and 5 are the factors of 20 then 20 is the multiple of 4 and 5 both.
