Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 642/704,488/773
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 642,488
Greatest Common Factor of Numerators i.e. GCF of 642,488 is 2 .
LCM of Denominators means LCM of 704,773 as per the given fractions.
LCM of 704,773 is 544192 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 642,488
2 | 642, 488 |
321, 244 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 488
List of positive integer factors of 488 that divides 488 without a remainder.
1,2,4,8,61,122,244,488
Greatest Common Factor
We found the factors 642,488 . The biggest common factor number is the GCF number.
So the greatest common factor 642,488 is 2.
Lets's calculate LCM of 704,773
Given numbers has no common factors except 1. So, there LCM is their product i.e 544192
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/544192
Therefore, the GCF of Fractions 642/704,488/773 is 2/544192
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 704,773 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(704,773) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(704,773) x common factors =1 x 1 = 1
LCM(704,773) = ( 704 × 773 ) / 1
LCM(704,773) = 544192 / 1
LCM(704,773) = 544192
Here are some samples of GCF of Fractions calculations.
