Fist—take LCM or prime factors of these numbers---- the LCM of these numbers=240=2×2×2×2×3×5
Second—Now we have to cut the answers by dividing the numbers which are by themselves,As a square is,the number’s multiplication to itself.So the numbers which we are dividing to the prime factors which are alone must be divided by the answer of the LCM also.Now ,2×2×2×2×3×5/3×5=240/3×5.In this we are dividing them with 3×5=15 because they are alone.2×2×2×2=240/15
16=16,16 which is a square of 4 . 16 Answer!!!
