Least Common Multiple of 850,555,740 with GCF Formula

Least Common Multiple of 850,555,740 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 850,555,740 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(850,555,740) = 5

common factors(in case of two or more numbers have common factors) = 370

GCF(850,555,740) x common factors =5 x 370 = 1850

LCM(850,555,740) = ( 850 × 555 × 740 ) / 1850

LCM(850,555,740) = 349095000 / 1850

LCM(850,555,740) = 188700
