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 488,498
Greatest Common Factor of Numerators i.e. GCF of 488,498 is 2 .
LCM of Denominators means LCM of 874,781 as per the given fractions.
LCM of 874,781 is 682594 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 488,498
2 | 488, 498 |
244, 249 |
∴ So the GCF of the given numbers is 2 = 2

1,2,3,6,83,166,249,498
Greatest Common Factor
We found the factors 488,498 . The biggest common factor number is the GCF number.
So the greatest common factor 488,498 is 2.
Lets's calculate LCM of 874,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 682594
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/682594
Therefore, the GCF of Fractions 488/874,498/781 is 2/682594
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 874,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(874,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(874,781) x common factors =1 x 1 = 1
LCM(874,781) = ( 874 × 781 ) / 1
LCM(874,781) = 682594 / 1
LCM(874,781) = 682594
Here are some samples of GCF of Fractions calculations.
