Question

find the smallest perfect square which is divisible bt 8, 12 and 15.​

Answer 1

Answer:

3600

Step-by-step explanation:

Let us find LCM of 8,15 and 20  

8 = 2 × 2 × 2

15 = 3 × 5

20 = 2 × 2 × 5  

So, LCM = 2 × 2 × 2 × 3 × 5 = 120.

For numbers which are not in pairs in LCM factors, we need to multiply 120 by 2, 3 and 5 to make it a perfect square.  

Required Number = 120 × 2 × 3 × 5 = 3600

Answer 2

8 = 2*2*2 = To get a perfect square, we have to multiply by 2.

12= 2*2*3 = To get a perfect square, we have to multiply by 3.

15= 3*5 = To get a perfect square, we have to multiply by 3*5=15

Hope it helps.
