GCF of Denominators means GCF of 39,31,765 as per the given fractions.

GCF of 39,31,765 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 121,789,205

LCM of Fractions 121/39,789/31,205/765 is 19571145

Given numbers has no common factors except 1. So, there LCM is their product i.e 19571145

Least Common Multiple of 121,789,205 with GCF Formula

Least Common Multiple of 121,789,205 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 121,789,205 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(121,789,205) = 1

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

GCF(121,789,205) x common factors =1 x 1 = 1

LCM(121,789,205) = ( 121 × 789 × 205 ) / 1

LCM(121,789,205) = 19571145 / 1

LCM(121,789,205) = 19571145


Lets's calculate GCF of 39,31,765

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 19571145/1

Therefore the LCM of Fractions 121/39,789/31,205/765 is 19571145
