Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 760/78,640/2495
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 760,640
Greatest Common Factor of Numerators i.e. GCF of 760,640 is 40 .
LCM of Denominators means LCM of 78,2495 as per the given fractions.
LCM of 78,2495 is 194610 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 760,640
2 | 760, 640 |
2 | 380, 320 |
2 | 190, 160 |
5 | 95, 80 |
19, 16 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 5 = 40

Greatest Common Factor
We found the factors 760,640 . The biggest common factor number is the GCF number.
So the greatest common factor 760,640 is 40.
Lets's calculate LCM of 78,2495
Given numbers has no common factors except 1. So, there LCM is their product i.e 194610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 40/194610
Therefore, the GCF of Fractions 760/78,640/2495 is 40/194610
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 78,2495 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,2495) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(78,2495) x common factors =1 x 1 = 1
LCM(78,2495) = ( 78 × 2495 ) / 1
LCM(78,2495) = 194610 / 1
LCM(78,2495) = 194610
Here are some samples of GCF of Fractions calculations.
