Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 7/99,704/61,641/31
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 7,704,641
Greatest Common Factor of Numerators i.e. GCF of 7,704,641 is 1 .
LCM of Denominators means LCM of 99,61,31 as per the given fractions.
LCM of 99,61,31 is 187209 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 7,704,641
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,4,8,11,16,22,32,44,64,88,176,352,704
Factors of 641
List of positive integer factors of 641 that divides 641 without a remainder.
1,641
Greatest Common Factor
We found the factors 7,704,641 . The biggest common factor number is the GCF number.
So the greatest common factor 7,704,641 is 1.
Lets's calculate LCM of 99,61,31
Given numbers has no common factors except 1. So, there LCM is their product i.e 187209
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/187209
Therefore, the GCF of Fractions 7/99,704/61,641/31 is 1/187209
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 99,61,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,61,31) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(99,61,31) x common factors =1 x 1 = 1
LCM(99,61,31) = ( 99 × 61 × 31 ) / 1
LCM(99,61,31) = 187209 / 1
LCM(99,61,31) = 187209
