Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 641/455,6729/124
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 641,6729
Greatest Common Factor of Numerators i.e. GCF of 641,6729 is 1 .
LCM of Denominators means LCM of 455,124 as per the given fractions.
LCM of 455,124 is 56420 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 641,6729
∴ So GCF of numbers is 1 because of no common factors present between them.

1,641
Factors of 6729
List of positive integer factors of 6729 that divides 6729 without a remainder.
1,3,2243,6729
Greatest Common Factor
We found the factors 641,6729 . The biggest common factor number is the GCF number.
So the greatest common factor 641,6729 is 1.
Lets's calculate LCM of 455,124
Given numbers has no common factors except 1. So, there LCM is their product i.e 56420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/56420
Therefore, the GCF of Fractions 641/455,6729/124 is 1/56420
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 455,124 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(455,124) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(455,124) x common factors =1 x 1 = 1
LCM(455,124) = ( 455 × 124 ) / 1
LCM(455,124) = 56420 / 1
LCM(455,124) = 56420
