Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 644/98,451/1996
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 644,451
Greatest Common Factor of Numerators i.e. GCF of 644,451 is 1 .
LCM of Denominators means LCM of 98,1996 as per the given fractions.
LCM of 98,1996 is 97804 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 644,451
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 644 that divides 644 without a remainder.
1,2,4,7,14,23,28,46,92,161,322,644
Factors of 451
List of positive integer factors of 451 that divides 451 without a remainder.
1,11,41,451
Greatest Common Factor
We found the factors 644,451 . The biggest common factor number is the GCF number.
So the greatest common factor 644,451 is 1.
Lets's calculate LCM of 98,1996
2 | 98, 1996 |
49, 998 |
∴ So the LCM of the given numbers is 2 x 49 x 998 = 97804
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/97804
Therefore, the GCF of Fractions 644/98,451/1996 is 1/97804
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 98,1996 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,1996) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(98,1996) x common factors =2 x 1 = 2
LCM(98,1996) = ( 98 × 1996 ) / 2
LCM(98,1996) = 195608 / 2
LCM(98,1996) = 97804
