Least Common Multiple of 640,470,100,451 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 640,470,100,451 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(640,470,100,451) = 1

common factors(in case of two or more numbers have common factors) = 200

GCF(640,470,100,451) x common factors =1 x 200 = 200

LCM(640,470,100,451) = ( 640 × 470 × 100 × 451 ) / 200

LCM(640,470,100,451) = 13566080000 / 200

LCM(640,470,100,451) = 67830400

∴ Least Common Multiple of 640,470,100,451 is 67830400
