Question

4) If a number is divisible by 5 and 12 then by which other number will it be divisible. ​

Answer 1

Answer:

5 and 12 are co-primes and we know that if a number is divisble by two co-primes, then it is a known fact that it is also divisible by their product.

The product of 5 and 12 is 60. Hence, the number is always divisible by 60.
