Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 50/97,65/17,642/392
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 50,65,642
Greatest Common Factor of Numerators i.e. GCF of 50,65,642 is 1 .
LCM of Denominators means LCM of 97,17,392 as per the given fractions.
LCM of 97,17,392 is 646408 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 50,65,642
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 50
List of positive integer factors of 50 that divides 50 without a remainder.
1,2,5,10,25,50

Factors of 642
List of positive integer factors of 642 that divides 642 without a remainder.
1,2,3,6,107,214,321,642
Greatest Common Factor
We found the factors 50,65,642 . The biggest common factor number is the GCF number.
So the greatest common factor 50,65,642 is 1.
Lets's calculate LCM of 97,17,392
Given numbers has no common factors except 1. So, there LCM is their product i.e 646408
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/646408
Therefore, the GCF of Fractions 50/97,65/17,642/392 is 1/646408
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 97,17,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,17,392) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,17,392) x common factors =1 x 1 = 1
LCM(97,17,392) = ( 97 × 17 × 392 ) / 1
LCM(97,17,392) = 646408 / 1
LCM(97,17,392) = 646408
Here are some samples of GCF of Fractions calculations.
