Greatest Common Factor of 14/68,20/68,39/71,18/56

Given fractions are 14/68,20/68,39/71,18/56

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 14,20,39,18

Greatest Common Factor of Numerators i.e. GCF of 14,20,39,18 is 1 .

LCM of Denominators means LCM of 68,68,71,56 as per the given fractions.

LCM of 68,68,71,56 is 67592 as it is the smallest common factor for both these numbers.

Lets's calculate GCF of 14,20,39,18

Greatest Common Factor

We found the factors 14,20,39,18 . The biggest common factor number is the GCF number.
So the greatest common factor 14,20,39,18 is 1.

Lets's calculate LCM of 68,68,71,56

2 68, 68, 71, 56
2 34, 34, 71, 28
17 17, 17, 71, 14
1, 1, 71, 14

∴ So the LCM of the given numbers is 2 x 2 x 17 x 1 x 1 x 71 x 14 = 67592

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/67592

Therefore, the GCF of Fractions 14/68,20/68,39/71,18/56 is 1/67592

Least Common Multiple of 68,68,71,56 with GCF Formula

Least Common Multiple of 68,68,71,56 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 68,68,71,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,68,71,56) = 1

common factors(in case of two or more numbers have common factors) = 272

GCF(68,68,71,56) x common factors =1 x 272 = 272

LCM(68,68,71,56) = ( 68 × 68 × 71 × 56 ) / 272

LCM(68,68,71,56) = 18385024 / 272

LCM(68,68,71,56) = 67592
