Least Common Multiple of 7128,2640 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 7128,2640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7128,2640) = 264

common factors(in case of two or more numbers have common factors) = 1

GCF(7128,2640) x common factors =264 x 1 = 264

LCM(7128,2640) = ( 7128 × 2640 ) / 264

LCM(7128,2640) = 18817920 / 264

LCM(7128,2640) = 71280

∴ Least Common Multiple of 7128,2640 is 71280
