Least Common Multiple of 420,640,468 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 420,640,468 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,640,468) = 4

common factors(in case of two or more numbers have common factors) = 60

GCF(420,640,468) x common factors =4 x 60 = 240

LCM(420,640,468) = ( 420 × 640 × 468 ) / 240

LCM(420,640,468) = 125798400 / 240

LCM(420,640,468) = 524160

∴ Least Common Multiple of 420,640,468 is 524160
