Least Common Multiple of 7980,9120 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 7980,9120 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7980,9120) = 1140

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

GCF(7980,9120) x common factors =1140 x 1 = 1140

LCM(7980,9120) = ( 7980 × 9120 ) / 1140

LCM(7980,9120) = 72777600 / 1140

LCM(7980,9120) = 63840

∴ Least Common Multiple of 7980,9120 is 63840
