Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 665/799,460/172
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 665,460
Greatest Common Factor of Numerators i.e. GCF of 665,460 is 5 .
LCM of Denominators means LCM of 799,172 as per the given fractions.
LCM of 799,172 is 137428 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 665,460
5 | 665, 460 |
133, 92 |
∴ So the GCF of the given numbers is 5 = 5

1,2,4,5,10,20,23,46,92,115,230,460
Greatest Common Factor
We found the factors 665,460 . The biggest common factor number is the GCF number.
So the greatest common factor 665,460 is 5.
Lets's calculate LCM of 799,172
Given numbers has no common factors except 1. So, there LCM is their product i.e 137428
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/137428
Therefore, the GCF of Fractions 665/799,460/172 is 5/137428
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 799,172 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(799,172) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(799,172) x common factors =1 x 1 = 1
LCM(799,172) = ( 799 × 172 ) / 1
LCM(799,172) = 137428 / 1
LCM(799,172) = 137428
Here are some samples of GCF of Fractions calculations.
