Least Common Multiple of 21,64,136,546 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 21,64,136,546 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,64,136,546) = 1

common factors(in case of two or more numbers have common factors) = 336

GCF(21,64,136,546) x common factors =1 x 336 = 336

LCM(21,64,136,546) = ( 21 × 64 × 136 × 546 ) / 336

LCM(21,64,136,546) = 99800064 / 336

LCM(21,64,136,546) = 297024

∴ Least Common Multiple of 21,64,136,546 is 297024
