Answer 2

Answer:

The smallest square number which is divisible by 4, 6 and 10 is 900.

Step-by-step explanation:

L.C.M of 4, 6, 10 = 2 × 2 × 3 × 5

So, the prime factor 3 and 5 does not have a pair, so multiply = 3 × 5 = 15 with the L.C.M

2 × 2 × 3 × 3 × 5 × 5 = 900

√900 = 2 × 3 × 5

          = 30

The smallest square number which is divisible by 4, 6 and 10 is 900.
