If a number is divisible by another number,
It is divisible by all the factors of the number
Example 1
If a number is divisible by 6,
it is divisible by all the factors of 6
Factors of 6 are
1 × 6 = 6
2 × 3 = 6
3 × 2 = 6
We stop here as 2 & 3 have occurred earlier
So, factors of 6 are 1, 2, 3, 6
So if a number is divisible 6
It is divisible by its factors 1, 2, 3, 6
Example 2
If a number is divisible by 18,
it is divisible by all the factors of 18
Factors of 18 are
1 × 18 = 18
2 × 9 = 18
3 × 6 = 18
6 × 3 = 18
We stop here as 6 & 3 have occurred earlier
So, factors of 18 are 1, 2, 3, 6, 9, 18
So if a number is divisible 18
It is divisible by its factors 1, 2, 3, 6, 9, 18
