Least Common Multiple of 5740,7840 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 5740,7840 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(5740,7840) = 140

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

GCF(5740,7840) x common factors =140 x 1 = 140

LCM(5740,7840) = ( 5740 × 7840 ) / 140

LCM(5740,7840) = 45001600 / 140

LCM(5740,7840) = 321440

∴ Least Common Multiple of 5740,7840 is 321440
