GCF of 55,43,15 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 485,691,642

LCM of Fractions 485/55,691/43,642/15 is 215156670

Given numbers has no common factors except 1. So, there LCM is their product i.e 215156670

Least Common Multiple of 485,691,642 with GCF Formula

Least Common Multiple of 485,691,642 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 485,691,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(485,691,642) = 1

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

GCF(485,691,642) x common factors =1 x 1 = 1

LCM(485,691,642) = ( 485 × 691 × 642 ) / 1

LCM(485,691,642) = 215156670 / 1

LCM(485,691,642) = 215156670


Lets's calculate GCF of 55,43,15

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 215156670/1

Therefore the LCM of Fractions 485/55,691/43,642/15 is 215156670
