LCM of 84, 400, 400

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 84,400,400

Least Common Multiple (LCM) of 84,400,400 is 8400

2 84, 400, 400
2 42, 200, 200
2 21, 100, 100
2 21, 50, 50
5 21, 25, 25
5 21, 5, 5
21, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 5 x 21 x 1 x 1 = 8400

Least Common Multiple of 84,400,400 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 84,400,400 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,400,400) = 4

common factors(in case of two or more numbers have common factors) = 400

GCF(84,400,400) x common factors =4 x 400 = 1600

LCM(84,400,400) = ( 84 × 400 × 400 ) / 1600

LCM(84,400,400) = 13440000 / 1600

LCM(84,400,400) = 8400

∴ Least Common Multiple of 84,400,400 is 8400
