Least Common Multiple of 72,90,99,192 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 72,90,99,192 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,90,99,192) = 3

common factors(in case of two or more numbers have common factors) = 1296

GCF(72,90,99,192) x common factors =3 x 1296 = 3888

LCM(72,90,99,192) = ( 72 × 90 × 99 × 192 ) / 3888

LCM(72,90,99,192) = 123171840 / 3888

LCM(72,90,99,192) = 31680

∴ Least Common Multiple of 72,90,99,192 is 31680
