Question

find the least squares number exactly divisible by each of following numbers
8,9,10​

Answer 1

we need to calculate LCM for this.....

1st we need to write them as product of primes

8 = 2*2*2

9 = 3*3

10 = 2*5

LCM = product of primes with highest powers

        = 2^3 * 3^2 * 5

        = 8 * 9 * 5

        = 360

360 is the answer

hope it helps you
