Question

10. Find the smallest square number that is divisible by each of the numbers 8,15 and 20.
​

Answer 1

Answer:

The number that is perfectly divisible by each of the numbers 8, 15, and 20 is their LCM.

Here, prime factors 2, 3, and 5 do not have their respective pairs.

Therefore, 120 is not a perfect square. Therefore, 120 should be multiplied by 2 × 3 × 5, i.e. 30, to obtain a perfect square.

30 is your answer

Answer 2

Answer:

30 is the right answer...
