LCM of:

Least Common Multiple of 64,16,400,392

Least Common Multiple (LCM) of 64,16,400,392 is 78400

2 64, 16, 400, 392
2 32, 8, 200, 196
2 16, 4, 100, 98
2 8, 2, 50, 49
4, 1, 25, 49

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 4 x 1 x 25 x 49 = 78400

Least Common Multiple of 64,16,400,392 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 64,16,400,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(64,16,400,392) = 8

common factors(in case of two or more numbers have common factors) = 256

GCF(64,16,400,392) x common factors =8 x 256 = 2048

LCM(64,16,400,392) = ( 64 × 16 × 400 × 392 ) / 2048

LCM(64,16,400,392) = 160563200 / 2048

LCM(64,16,400,392) = 78400

∴ Least Common Multiple of 64,16,400,392 is 78400
