Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 18/77,13/74,92/17,49/989
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 18,13,92,49
Greatest Common Factor of Numerators i.e. GCF of 18,13,92,49 is 1 .
LCM of Denominators means LCM of 77,74,17,989 as per the given fractions.
LCM of 77,74,17,989 is 95800474 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 18,13,92,49
∴ So GCF of numbers is 1 because of no common factors present between them.

1,13
Factors of 92
List of positive integer factors of 92 that divides 92 without a remainder.
1,2,4,23,46,92
Factors of 49
List of positive integer factors of 49 that divides 49 without a remainder.
1,7,49
Greatest Common Factor
We found the factors 18,13,92,49 . The biggest common factor number is the GCF number.
So the greatest common factor 18,13,92,49 is 1.
Lets's calculate LCM of 77,74,17,989
Given numbers has no common factors except 1. So, there LCM is their product i.e 95800474
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/95800474
Therefore, the GCF of Fractions 18/77,13/74,92/17,49/989 is 1/95800474
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 77,74,17,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,74,17,989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,74,17,989) x common factors =1 x 1 = 1
LCM(77,74,17,989) = ( 77 × 74 × 17 × 989 ) / 1
LCM(77,74,17,989) = 95800474 / 1
LCM(77,74,17,989) = 95800474
Here are some samples of GCF of Fractions calculations.
