Least Common Multiple of 840,105,320 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 840,105,320 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(840,105,320) = 5

common factors(in case of two or more numbers have common factors) = 840

GCF(840,105,320) x common factors =5 x 840 = 4200

LCM(840,105,320) = ( 840 × 105 × 320 ) / 4200

LCM(840,105,320) = 28224000 / 4200

LCM(840,105,320) = 6720

∴ Least Common Multiple of 840,105,320 is 6720
