Least Common Multiple of 720,120,654 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 720,120,654 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(720,120,654) = 6

common factors(in case of two or more numbers have common factors) = 120

GCF(720,120,654) x common factors =6 x 120 = 720

LCM(720,120,654) = ( 720 × 120 × 654 ) / 720

LCM(720,120,654) = 56505600 / 720

LCM(720,120,654) = 78480

∴ Least Common Multiple of 720,120,654 is 78480
