Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 117/79,642/4470
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 117,642
Greatest Common Factor of Numerators i.e. GCF of 117,642 is 3 .
LCM of Denominators means LCM of 79,4470 as per the given fractions.
LCM of 79,4470 is 353130 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 117,642
3 | 117, 642 |
39, 214 |
∴ So the GCF of the given numbers is 3 = 3

1,2,3,6,107,214,321,642
Greatest Common Factor
We found the factors 117,642 . The biggest common factor number is the GCF number.
So the greatest common factor 117,642 is 3.
Lets's calculate LCM of 79,4470
Given numbers has no common factors except 1. So, there LCM is their product i.e 353130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/353130
Therefore, the GCF of Fractions 117/79,642/4470 is 3/353130
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 79,4470 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,4470) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,4470) x common factors =1 x 1 = 1
LCM(79,4470) = ( 79 × 4470 ) / 1
LCM(79,4470) = 353130 / 1
LCM(79,4470) = 353130
