Least Common Multiple of 78,85,18,286 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 78,85,18,286 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,85,18,286) = 1

common factors(in case of two or more numbers have common factors) = 156

GCF(78,85,18,286) x common factors =1 x 156 = 156

LCM(78,85,18,286) = ( 78 × 85 × 18 × 286 ) / 156

LCM(78,85,18,286) = 34131240 / 156

LCM(78,85,18,286) = 218790

∴ Least Common Multiple of 78,85,18,286 is 218790
