Least Common Multiple of 756,840,860 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 756,840,860 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(756,840,860) = 4

common factors(in case of two or more numbers have common factors) = 420

GCF(756,840,860) x common factors =4 x 420 = 1680

LCM(756,840,860) = ( 756 × 840 × 860 ) / 1680

LCM(756,840,860) = 546134400 / 1680

LCM(756,840,860) = 325080

∴ Least Common Multiple of 756,840,860 is 325080
