Given numbers are 77/399,189/572,979/285

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 77,189,979

Least Common Multiple of Numerators i.e. LCM of 77,189,979 is 185031.

GCF of Denominators means GCF of 399,572,285 as per the given fractions.

GCF of 399,572,285 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 77,189,979

LCM of Fractions 77/399,189/572,979/285 is 185031

7 77, 189, 979
11 11, 27, 979
1, 27, 89

∴ So the LCM of the given numbers is 7 x 11 x 1 x 27 x 89 = 185031

Least Common Multiple of 77,189,979 with GCF Formula

Least Common Multiple of 77,189,979 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 77,189,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,189,979) = 1

common factors(in case of two or more numbers have common factors) = 77

GCF(77,189,979) x common factors =1 x 77 = 77

LCM(77,189,979) = ( 77 × 189 × 979 ) / 77

LCM(77,189,979) = 14247387 / 77

LCM(77,189,979) = 185031


Lets's calculate GCF of 399,572,285

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 185031/1

Therefore the LCM of Fractions 77/399,189/572,979/285 is 185031
