Question

A number is divisible by both 5 and 9.By which other number will that number be always divisible?​

Answer 1

Let's say 90 is divisible by 5 and 9. As we know 5 and 9 are co-prime numbers. Therefore, 90 is divisible by product of the co-primes i,e 5 and 9. If two given numbers are divisible by a number, then, their sum is also divisible by that number.
