Question

find the smallest perfect square that is divisible by 15 20 and 25​

Answer 1

Step-by-step explanation:

12 = 2 x 2 x 3

15 = 3 x 5

20 = 2 x 2 x 5

So, LCM = 2 x 2 x 3 x 5 = 60

As 3 and 5 are not in pair in LCM’s factor so we need to multiply 60 by 5 and 3 .

Required Smallest Number = 60 x 3 x 5 = 900.
