Question

Find the least number which is a perfect square and which is also divisible by 16, 18 and 45​

Answer 1

Answer:

we have to find the Lcm of 16, 18,& 45

16= 2×2×2×2

18= 2×3×3

45= 3× 3×5

LCM =2²× 2²× 3²×5 = 720

5 is not in pair so we should multiply 720 by 5 to get a required number

720× 5 = 3600

Hence the required least number which is a perfect Square is 3600.
