Least Common Multiple of 640,7812,126 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 640,7812,126 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(640,7812,126) = 2

common factors(in case of two or more numbers have common factors) = 252

GCF(640,7812,126) x common factors =2 x 252 = 504

LCM(640,7812,126) = ( 640 × 7812 × 126 ) / 504

LCM(640,7812,126) = 629959680 / 504

LCM(640,7812,126) = 1249920

∴ Least Common Multiple of 640,7812,126 is 1249920
