Greatest Common Factor of 23/84,43/51,36/91

Given fractions are 23/84,43/51,36/91

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 23,43,36

Greatest Common Factor of Numerators i.e. GCF of 23,43,36 is 1 .

LCM of Denominators means LCM of 84,51,91 as per the given fractions.

LCM of 84,51,91 is 18564 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 23,43,36

GCF of Fractions 23/84,43/51,36/91 is 1/18564

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

Greatest Common Factor

We found the factors 23,43,36 . The biggest common factor number is the GCF number.
So the greatest common factor 23,43,36 is 1.

Lets's calculate LCM of 84,51,91

3 84, 51, 91
7 28, 17, 91
4, 17, 13

∴ So the LCM of the given numbers is 3 x 7 x 4 x 17 x 13 = 18564

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18564

Therefore, the GCF of Fractions 23/84,43/51,36/91 is 1/18564

Least Common Multiple of 84,51,91 with GCF Formula

Least Common Multiple of 84,51,91 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 84,51,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,51,91) = 1

common factors(in case of two or more numbers have common factors) = 21

GCF(84,51,91) x common factors =1 x 21 = 21

LCM(84,51,91) = ( 84 × 51 × 91 ) / 21

LCM(84,51,91) = 389844 / 21

LCM(84,51,91) = 18564
