Least Common Multiple of 421,728,715,121 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 421,728,715,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(421,728,715,121) = 1

common factors(in case of two or more numbers have common factors) = 143

GCF(421,728,715,121) x common factors =1 x 143 = 143

LCM(421,728,715,121) = ( 421 × 728 × 715 × 121 ) / 143

LCM(421,728,715,121) = 26515809320 / 143

LCM(421,728,715,121) = 185425240

∴ Least Common Multiple of 421,728,715,121 is 185425240
