Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 1639/17,1220/521
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 1639,1220
Greatest Common Factor of Numerators i.e. GCF of 1639,1220 is 1 .
LCM of Denominators means LCM of 17,521 as per the given fractions.
LCM of 17,521 is 8857 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 1639,1220
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 1639 that divides 1639 without a remainder.
1,11,149,1639
Factors of 1220
List of positive integer factors of 1220 that divides 1220 without a remainder.
1,2,4,5,10,20,61,122,244,305,610,1220
Greatest Common Factor
We found the factors 1639,1220 . The biggest common factor number is the GCF number.
So the greatest common factor 1639,1220 is 1.
Lets's calculate LCM of 17,521
Given numbers has no common factors except 1. So, there LCM is their product i.e 8857
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8857
Therefore, the GCF of Fractions 1639/17,1220/521 is 1/8857
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 17,521 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,521) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,521) x common factors =1 x 1 = 1
LCM(17,521) = ( 17 × 521 ) / 1
LCM(17,521) = 8857 / 1
LCM(17,521) = 8857
