LCM of:

Least Common Multiple of 840,280

Least Common Multiple (LCM) of 840,280 is 840

2 840, 280
2 420, 140
2 210, 70
5 105, 35
7 21, 7
3, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 7 x 3 x 1 = 840

Least Common Multiple of 840,280 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 840,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(840,280) = 280

common factors(in case of two or more numbers have common factors) = 1

GCF(840,280) x common factors =280 x 1 = 280

LCM(840,280) = ( 840 × 280 ) / 280

LCM(840,280) = 235200 / 280

LCM(840,280) = 840

∴ Least Common Multiple of 840,280 is 840
