Least Common Multiple of 987,931,813,420 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 987,931,813,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(987,931,813,420) = 1

common factors(in case of two or more numbers have common factors) = 441

GCF(987,931,813,420) x common factors =1 x 441 = 441

LCM(987,931,813,420) = ( 987 × 931 × 813 × 420 ) / 441

LCM(987,931,813,420) = 313766569620 / 441

LCM(987,931,813,420) = 711488820

∴ Least Common Multiple of 987,931,813,420 is 711488820
