Divisibility is the ability of a number (the dividend) to be completely divisible by another number (divisor) without any remainder.
This means that the numbers that completely divide this larger number are its factors.
For example:
10 is completely divisible by 1, 2, 5, and 10. This means that each of the se numbers can divide 10 completely without any remainder.
The process (steps) of divisibilty is to keep dividing the number until there is no remainder.
Let us use an example to demonstrate the steps
100 divided by 5 = 21
From the above, we can see that 5 is a factor of 105 because it divides it completely with no remainder.
