Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 380/47,4979/642
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 380,4979
Greatest Common Factor of Numerators i.e. GCF of 380,4979 is 1 .
LCM of Denominators means LCM of 47,642 as per the given fractions.
LCM of 47,642 is 30174 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 380,4979
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 380 that divides 380 without a remainder.
1,2,4,5,10,19,20,38,76,95,190,380
Factors of 4979
List of positive integer factors of 4979 that divides 4979 without a remainder.
1,13,383,4979
Greatest Common Factor
We found the factors 380,4979 . The biggest common factor number is the GCF number.
So the greatest common factor 380,4979 is 1.
Lets's calculate LCM of 47,642
Given numbers has no common factors except 1. So, there LCM is their product i.e 30174
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30174
Therefore, the GCF of Fractions 380/47,4979/642 is 1/30174
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 47,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,642) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,642) x common factors =1 x 1 = 1
LCM(47,642) = ( 47 × 642 ) / 1
LCM(47,642) = 30174 / 1
LCM(47,642) = 30174
