Question

The smallest square number which is divisible by each number 6,9and15 is​

Answer 1

 

Take the LCM of the given numbers 6, 9 and 15. So that LCM = 90. Factorise this 90, such that,

90 = 2 × 3² × 5.

To make 90 a perfect square (smallest), multiple 2 × 5 = 10 with 90 because there are only one 2 and one 5 in the factorisation of 90. So we get 90 × 10 = 900. This is the answer.
