GCF of:

Greatest Common Factor of 1/45,2/79,5/79,40/891

Given fractions are 1/45,2/79,5/79,40/891

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 1,2,5,40

Greatest Common Factor of Numerators i.e. GCF of 1,2,5,40 is 1 .

LCM of Denominators means LCM of 45,79,79,891 as per the given fractions.

LCM of 45,79,79,891 is 351945 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 1,2,5,40

GCF of Fractions 1/45,2/79,5/79,40/891 is 1/351945

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

So the greatest common factor 1,2,5,40 is 1.

Lets's calculate LCM of 45,79,79,891

3 45, 79, 79, 891
3 15, 79, 79, 297
79 5, 79, 79, 99
5, 1, 1, 99

∴ So the LCM of the given numbers is 3 x 3 x 79 x 5 x 1 x 1 x 99 = 351945

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/351945

Therefore, the GCF of Fractions 1/45,2/79,5/79,40/891 is 1/351945

Least Common Multiple of 45,79,79,891 with GCF Formula

Least Common Multiple of 45,79,79,891 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 45,79,79,891 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,79,79,891) = 1

common factors(in case of two or more numbers have common factors) = 711

GCF(45,79,79,891) x common factors =1 x 711 = 711

LCM(45,79,79,891) = ( 45 × 79 × 79 × 891 ) / 711

LCM(45,79,79,891) = 250232895 / 711

LCM(45,79,79,891) = 351945
