Least Common Multiple of 643,6840

Least Common Multiple (LCM) of 643,6840 is 4398120

Given numbers has no common factors except 1. So, there LCM is their product i.e 4398120

Least Common Multiple of 643,6840 with GCF Formula

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

We need to calculate greatest common factor of 643,6840 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,6840) = 1

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

GCF(643,6840) x common factors =1 x 1 = 1

LCM(643,6840) = ( 643 × 6840 ) / 1

LCM(643,6840) = 4398120 / 1

LCM(643,6840) = 4398120

∴ Least Common Multiple of 643,6840 is 4398120
