Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 684/985,220/503
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 684,220
Greatest Common Factor of Numerators i.e. GCF of 684,220 is 4 .
LCM of Denominators means LCM of 985,503 as per the given fractions.
LCM of 985,503 is 495455 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 684,220
2 | 684, 220 |
2 | 342, 110 |
171, 55 |
∴ So the GCF of the given numbers is 2 x 2 = 4

1,2,4,5,10,11,20,22,44,55,110,220
Greatest Common Factor
We found the factors 684,220 . The biggest common factor number is the GCF number.
So the greatest common factor 684,220 is 4.
Lets's calculate LCM of 985,503
Given numbers has no common factors except 1. So, there LCM is their product i.e 495455
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/495455
Therefore, the GCF of Fractions 684/985,220/503 is 4/495455
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 985,503 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(985,503) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(985,503) x common factors =1 x 1 = 1
LCM(985,503) = ( 985 × 503 ) / 1
LCM(985,503) = 495455 / 1
LCM(985,503) = 495455
Here are some samples of GCF of Fractions calculations.
