Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 985/135,3121/780
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 985,3121
Greatest Common Factor of Numerators i.e. GCF of 985,3121 is 1 .
LCM of Denominators means LCM of 135,780 as per the given fractions.
LCM of 135,780 is 7020 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 985,3121
∴ So GCF of numbers is 1 because of no common factors present between them.

1,5,197,985
Factors of 3121
List of positive integer factors of 3121 that divides 3121 without a remainder.
1,3121
Greatest Common Factor
We found the factors 985,3121 . The biggest common factor number is the GCF number.
So the greatest common factor 985,3121 is 1.
Lets's calculate LCM of 135,780
3 | 135, 780 |
5 | 45, 260 |
9, 52 |
∴ So the LCM of the given numbers is 3 x 5 x 9 x 52 = 7020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7020
Therefore, the GCF of Fractions 985/135,3121/780 is 1/7020
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 135,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(135,780) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(135,780) x common factors =15 x 1 = 15
LCM(135,780) = ( 135 × 780 ) / 15
LCM(135,780) = 105300 / 15
LCM(135,780) = 7020
