Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 380/272,715/247
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 380,715
Greatest Common Factor of Numerators i.e. GCF of 380,715 is 5 .
LCM of Denominators means LCM of 272,247 as per the given fractions.
LCM of 272,247 is 67184 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 380,715
5 | 380, 715 |
76, 143 |
∴ So the GCF of the given numbers is 5 = 5

1,2,4,5,10,19,20,38,76,95,190,380
Factors of 715
List of positive integer factors of 715 that divides 715 without a remainder.
1,5,11,13,55,65,143,715
Greatest Common Factor
We found the factors 380,715 . The biggest common factor number is the GCF number.
So the greatest common factor 380,715 is 5.
Lets's calculate LCM of 272,247
Given numbers has no common factors except 1. So, there LCM is their product i.e 67184
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/67184
Therefore, the GCF of Fractions 380/272,715/247 is 5/67184
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 272,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(272,247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(272,247) x common factors =1 x 1 = 1
LCM(272,247) = ( 272 × 247 ) / 1
LCM(272,247) = 67184 / 1
LCM(272,247) = 67184
Here are some samples of GCF of Fractions calculations.
