Lets's calculate LCM of 571,818,645

LCM of Fractions 571/81,818/42,645/78 is 100421770

Given numbers has no common factors except 1. So, there LCM is their product i.e 301265310

Least Common Multiple of 571,818,645 with GCF Formula

Least Common Multiple of 571,818,645 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 571,818,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(571,818,645) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(571,818,645) x common factors =1 x 1 = 1

LCM(571,818,645) = ( 571 × 818 × 645 ) / 1

LCM(571,818,645) = 301265310 / 1

LCM(571,818,645) = 301265310


Lets's calculate GCF of 81,42,78

3 81, 42, 78
27, 14, 26

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 301265310/3

Therefore the LCM of Fractions 571/81,818/42,645/78 is 100421770
