GCF of:

Greatest Common Factor of 87/71,87/41,78/12

Given fractions are 87/71,87/41,78/12

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 87,87,78

Greatest Common Factor of Numerators i.e. GCF of 87,87,78 is 3 .

LCM of Denominators means LCM of 71,41,12 as per the given fractions.

LCM of 71,41,12 is 34932 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 87,87,78

Greatest Common Factor

We found the factors 87,87,78 . The biggest common factor number is the GCF number.
So the greatest common factor 87,87,78 is 3.

Lets's calculate LCM of 71,41,12

Given numbers has no common factors except 1. So, there LCM is their product i.e 34932

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/34932

Therefore, the GCF of Fractions 87/71,87/41,78/12 is 3/34932

Least Common Multiple of 71,41,12 with GCF Formula

Least Common Multiple of 71,41,12 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 71,41,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,41,12) = 1

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

GCF(71,41,12) x common factors =1 x 1 = 1

LCM(71,41,12) = ( 71 × 41 × 12 ) / 1

LCM(71,41,12) = 34932 / 1

LCM(71,41,12) = 34932
