Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 231/470,147/375
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 231,147
Greatest Common Factor of Numerators i.e. GCF of 231,147 is 21 .
LCM of Denominators means LCM of 470,375 as per the given fractions.
LCM of 470,375 is 35250 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 231,147
3 | 231, 147 |
7 | 77, 49 |
11, 7 |
∴ So the GCF of the given numbers is 3 x 7 = 21

1,3,7,11,21,33,77,231
Factors of 147
List of positive integer factors of 147 that divides 147 without a remainder.
1,3,7,21,49,147
Greatest Common Factor
We found the factors 231,147 . The biggest common factor number is the GCF number.
So the greatest common factor 231,147 is 21.
Lets's calculate LCM of 470,375
5 | 470, 375 |
94, 75 |
∴ So the LCM of the given numbers is 5 x 94 x 75 = 35250
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/35250
Therefore, the GCF of Fractions 231/470,147/375 is 21/35250
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 470,375 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(470,375) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(470,375) x common factors =5 x 1 = 5
LCM(470,375) = ( 470 × 375 ) / 5
LCM(470,375) = 176250 / 5
LCM(470,375) = 35250
