Greatest Common Factor of 43/31,44/65,424/21

Given fractions are 43/31,44/65,424/21

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 43,44,424

Greatest Common Factor of Numerators i.e. GCF of 43,44,424 is 1 .

LCM of Denominators means LCM of 31,65,21 as per the given fractions.

LCM of 31,65,21 is 42315 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 43,44,424

GCF of Fractions 43/31,44/65,424/21 is 1/42315

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

Greatest Common Factor

We found the factors 43,44,424 . The biggest common factor number is the GCF number.
So the greatest common factor 43,44,424 is 1.

Lets's calculate LCM of 31,65,21

Given numbers has no common factors except 1. So, there LCM is their product i.e 42315

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42315

Therefore, the GCF of Fractions 43/31,44/65,424/21 is 1/42315

Least Common Multiple of 31,65,21 with GCF Formula

Least Common Multiple of 31,65,21 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 31,65,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,65,21) = 1

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

GCF(31,65,21) x common factors =1 x 1 = 1

LCM(31,65,21) = ( 31 × 65 × 21 ) / 1

LCM(31,65,21) = 42315 / 1

LCM(31,65,21) = 42315
