Least Common Multiple of 1620,8820 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 1620,8820 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1620,8820) = 180

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

GCF(1620,8820) x common factors =180 x 1 = 180

LCM(1620,8820) = ( 1620 × 8820 ) / 180

LCM(1620,8820) = 14288400 / 180

LCM(1620,8820) = 79380

∴ Least Common Multiple of 1620,8820 is 79380
