Least Common Multiple of 85,23,137,411 with GCF Formula
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 85,23,137,411 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,23,137,411) = 1
common factors(in case of two or more numbers have common factors) = 137
GCF(85,23,137,411) x common factors =1 x 137 = 137
LCM(85,23,137,411) = ( 85 × 23 × 137 × 411 ) / 137
LCM(85,23,137,411) = 110080185 / 137
LCM(85,23,137,411) = 803505
