Question

Test of divisibility 48​

Answer 1

Answer:

48 = 4 × 12 but 4 and 12 are not co-prime. Therefore, it is not necessary that the number will be divisible by 48. 72 ÷ 4 = 18, so 72 is divisible by 4. 72 ÷ 12 = 6, so 72 is divisible by 12.

Answer 2

48 = 4 × 12 but 4 and 12 are not co-prime.

Therefore, it is not necessary that the number will be divisible by 48.

72 ÷ 4 = 18, so 72 is divisible by 4.

72 ÷ 12 = 6, so 72 is divisible by 12.
