Question

Find a number which is divisible by 15, 18 and 25 and is perfect square​

Answer 1

Answer:

Step-by-step explanation:

To find  a number which is divisible by 15,18 and 25 .

First find least common multiple of 15,18 and 25

L.C.M. of  15,18 and 25 =450

and the prime factorization of 450

but  450 is not a perfect square.

To make it perfect square, we need to multiply 2 to 450, we get 900.

Hence, 900 is the number which is divisible by 15,18 and 25 and is a perfect square.

Answer 2

To find a number which is divisible by 15,18 and 25 .

First find least common multiple of 15, 18 and 25.

LCM of 15,18and 25 = 450

and the prime factorisation of 450= 2×3×3×5×5

It implies 450 is not a perfect square .

To make it perfect square , we need to multiple 2 to 450, we get 900.

Hence, 900 is the number which is divisible by 15,18 and 25 and is a perfect square.
