Find the least square number which is divisible by 4, 8, 2, 6 and 12?
The least number which is divisible by 4, 8, 2, 6 and 12
= L.C.M. (2,4,6,8,12) = 24
Now, prime factorization of $$24=2^3\times3$$
Now to make it a perfect square, we need to multiply it by $$2\times3=6$$
=> The least square number which is divisible by 4, 8, 2, 6 and 12 = $$24\times6=144$$
