Q2. Find te smallest perfect square number which is divisible by each of the numbers 6 9 and 15​

Answer 1

Answer:

900

Step-by-step explanation:

First we have to take the L.C.M.  of  6 , 9 , 15  

L.C.M here is 90

90 = 2×3×3×5

So , to get smallest perfect square we should get pairs of prime numbers

So, we multiply a no. such that we get prime pairs

∵ (2×2) × (3×3) × (5×5) = 90 × 10 = 900 .
