Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 78/79,76/20,253/37
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 78,76,253
Greatest Common Factor of Numerators i.e. GCF of 78,76,253 is 1 .
LCM of Denominators means LCM of 79,20,37 as per the given fractions.
LCM of 79,20,37 is 58460 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 78,76,253
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 78

1,2,3,6,13,26,39,78
Factors of 76
List of positive integer factors of 76 that divides 76 without a remainder.
1,2,4,19,38,76
Factors of 253
List of positive integer factors of 253 that divides 253 without a remainder.
1,11,23,253
Greatest Common Factor
We found the factors 78,76,253 . The biggest common factor number is the GCF number.
So the greatest common factor 78,76,253 is 1.
Lets's calculate LCM of 79,20,37
Given numbers has no common factors except 1. So, there LCM is their product i.e 58460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/58460
Therefore, the GCF of Fractions 78/79,76/20,253/37 is 1/58460
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 79,20,37 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,20,37) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,20,37) x common factors =1 x 1 = 1
LCM(79,20,37) = ( 79 × 20 × 37 ) / 1
LCM(79,20,37) = 58460 / 1
LCM(79,20,37) = 58460
Here are some samples of GCF of Fractions calculations.
