Least Common Multiple of 1680,9660 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 1680,9660 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1680,9660) = 420

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

GCF(1680,9660) x common factors =420 x 1 = 420

LCM(1680,9660) = ( 1680 × 9660 ) / 420

LCM(1680,9660) = 16228800 / 420

LCM(1680,9660) = 38640

∴ Least Common Multiple of 1680,9660 is 38640
