Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 889/79,3904/639
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 889,3904
Greatest Common Factor of Numerators i.e. GCF of 889,3904 is 1 .
LCM of Denominators means LCM of 79,639 as per the given fractions.
LCM of 79,639 is 50481 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 889,3904
∴ So GCF of numbers is 1 because of no common factors present between them.

1,7,127,889
Factors of 3904
List of positive integer factors of 3904 that divides 3904 without a remainder.
1,2,4,8,16,32,61,64,122,244,488,976,1952,3904
Greatest Common Factor
We found the factors 889,3904 . The biggest common factor number is the GCF number.
So the greatest common factor 889,3904 is 1.
Lets's calculate LCM of 79,639
Given numbers has no common factors except 1. So, there LCM is their product i.e 50481
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/50481
Therefore, the GCF of Fractions 889/79,3904/639 is 1/50481
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 79,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,639) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,639) x common factors =1 x 1 = 1
LCM(79,639) = ( 79 × 639 ) / 1
LCM(79,639) = 50481 / 1
LCM(79,639) = 50481
