Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 776/384,640/157
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 776,640
Greatest Common Factor of Numerators i.e. GCF of 776,640 is 8 .
LCM of Denominators means LCM of 384,157 as per the given fractions.
LCM of 384,157 is 60288 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 776,640
2 | 776, 640 |
2 | 388, 320 |
2 | 194, 160 |
97, 80 |
∴ So the GCF of the given numbers is 2 x 2 x 2 = 8

1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
Greatest Common Factor
We found the factors 776,640 . The biggest common factor number is the GCF number.
So the greatest common factor 776,640 is 8.
Lets's calculate LCM of 384,157
Given numbers has no common factors except 1. So, there LCM is their product i.e 60288
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/60288
Therefore, the GCF of Fractions 776/384,640/157 is 8/60288
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 384,157 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(384,157) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(384,157) x common factors =1 x 1 = 1
LCM(384,157) = ( 384 × 157 ) / 1
LCM(384,157) = 60288 / 1
LCM(384,157) = 60288
Here are some samples of GCF of Fractions calculations.
