Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 77/37,41/143,129/642
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 77,41,129
Greatest Common Factor of Numerators i.e. GCF of 77,41,129 is 1 .
LCM of Denominators means LCM of 37,143,642 as per the given fractions.
LCM of 37,143,642 is 3396822 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 77,41,129
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 129 that divides 129 without a remainder.
1,3,43,129
Greatest Common Factor
We found the factors 77,41,129 . The biggest common factor number is the GCF number.
So the greatest common factor 77,41,129 is 1.
Lets's calculate LCM of 37,143,642
Given numbers has no common factors except 1. So, there LCM is their product i.e 3396822
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3396822
Therefore, the GCF of Fractions 77/37,41/143,129/642 is 1/3396822
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 37,143,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(37,143,642) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(37,143,642) x common factors =1 x 1 = 1
LCM(37,143,642) = ( 37 × 143 × 642 ) / 1
LCM(37,143,642) = 3396822 / 1
LCM(37,143,642) = 3396822
