Greatest Common Factor of 1/45,74/635,21/254

Given fractions are 1/45,74/635,21/254

Formula to find GCF of Fractions is

GCF = GCF of Numerators/LCM of Denominators

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

In the given fractions GCF of Numerators means GCF of 1,74,21

Greatest Common Factor of Numerators i.e. GCF of 1,74,21 is 1 .

LCM of Denominators means LCM of 45,635,254 as per the given fractions.

LCM of 45,635,254 is 11430 as it is the smallest common factor for both these numbers.

Least Common Multiple of 45,635,254 with GCF Formula

Least Common Multiple of 45,635,254 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 45,635,254 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,635,254) = 1

common factors(in case of two or more numbers have common factors) = 635

GCF(45,635,254) x common factors =1 x 635 = 635

LCM(45,635,254) = ( 45 × 635 × 254 ) / 635

LCM(45,635,254) = 7258050 / 635

LCM(45,635,254) = 11430
