GCF of:

Greatest Common Factor of 9/57,7/68,44/13,78/102

Given fractions are 9/57,7/68,44/13,78/102

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 9,7,44,78

Greatest Common Factor of Numerators i.e. GCF of 9,7,44,78 is 1 .

LCM of Denominators means LCM of 57,68,13,102 as per the given fractions.

LCM of 57,68,13,102 is 50388 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 9,7,44,78

Greatest Common Factor

We found the factors 9,7,44,78 . The biggest common factor number is the GCF number.
So the greatest common factor 9,7,44,78 is 1.

Lets's calculate LCM of 57,68,13,102

2 57, 68, 13, 102
3 57, 34, 13, 51
17 19, 34, 13, 17
19, 2, 13, 1

∴ So the LCM of the given numbers is 2 x 3 x 17 x 19 x 2 x 13 x 1 = 50388

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/50388

Therefore, the GCF of Fractions 9/57,7/68,44/13,78/102 is 1/50388

Least Common Multiple of 57,68,13,102 with GCF Formula

Least Common Multiple of 57,68,13,102 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 57,68,13,102 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(57,68,13,102) = 1

common factors(in case of two or more numbers have common factors) = 102

GCF(57,68,13,102) x common factors =1 x 102 = 102

LCM(57,68,13,102) = ( 57 × 68 × 13 × 102 ) / 102

LCM(57,68,13,102) = 5139576 / 102

LCM(57,68,13,102) = 50388
