GCF of:

Greatest Common Factor of 8/45,54/71,50/55,91/69

Given fractions are 8/45,54/71,50/55,91/69

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 8,54,50,91

Greatest Common Factor of Numerators i.e. GCF of 8,54,50,91 is 1 .

LCM of Denominators means LCM of 45,71,55,69 as per the given fractions.

LCM of 45,71,55,69 is 808335 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 8,54,50,91

Greatest Common Factor

We found the factors 8,54,50,91 . The biggest common factor number is the GCF number.
So the greatest common factor 8,54,50,91 is 1.

Lets's calculate LCM of 45,71,55,69

3 45, 71, 55, 69
5 15, 71, 55, 23
3, 71, 11, 23

∴ So the LCM of the given numbers is 3 x 5 x 3 x 71 x 11 x 23 = 808335

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/808335

Therefore, the GCF of Fractions 8/45,54/71,50/55,91/69 is 1/808335

Least Common Multiple of 45,71,55,69 with GCF Formula

Least Common Multiple of 45,71,55,69 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 45,71,55,69 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,71,55,69) = 1

common factors(in case of two or more numbers have common factors) = 15

GCF(45,71,55,69) x common factors =1 x 15 = 15

LCM(45,71,55,69) = ( 45 × 71 × 55 × 69 ) / 15

LCM(45,71,55,69) = 12125025 / 15

LCM(45,71,55,69) = 808335
