Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 171/93,3639/615
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 171,3639
Greatest Common Factor of Numerators i.e. GCF of 171,3639 is 3 .
LCM of Denominators means LCM of 93,615 as per the given fractions.
LCM of 93,615 is 19065 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 171,3639
3 | 171, 3639 |
57, 1213 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 3639
List of positive integer factors of 3639 that divides 3639 without a remainder.
1,3,1213,3639
Greatest Common Factor
We found the factors 171,3639 . The biggest common factor number is the GCF number.
So the greatest common factor 171,3639 is 3.
Lets's calculate LCM of 93,615
3 | 93, 615 |
31, 205 |
∴ So the LCM of the given numbers is 3 x 31 x 205 = 19065
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/19065
Therefore, the GCF of Fractions 171/93,3639/615 is 3/19065
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 93,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(93,615) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(93,615) x common factors =3 x 1 = 3
LCM(93,615) = ( 93 × 615 ) / 3
LCM(93,615) = 57195 / 3
LCM(93,615) = 19065
