Least Common Multiple of 81,78,78,942 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 81,78,78,942 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,78,78,942) = 3

common factors(in case of two or more numbers have common factors) = 468

GCF(81,78,78,942) x common factors =3 x 468 = 1404

LCM(81,78,78,942) = ( 81 × 78 × 78 × 942 ) / 1404

LCM(81,78,78,942) = 464221368 / 1404

LCM(81,78,78,942) = 330642

∴ Least Common Multiple of 81,78,78,942 is 330642
