Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 234/19,171/257
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 234,171
Greatest Common Factor of Numerators i.e. GCF of 234,171 is 9 .
LCM of Denominators means LCM of 19,257 as per the given fractions.
LCM of 19,257 is 4883 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 234,171
3 | 234, 171 |
3 | 78, 57 |
26, 19 |
∴ So the GCF of the given numbers is 3 x 3 = 9

1,2,3,6,9,13,18,26,39,78,117,234
Factors of 171
List of positive integer factors of 171 that divides 171 without a remainder.
1,3,9,19,57,171
Greatest Common Factor
We found the factors 234,171 . The biggest common factor number is the GCF number.
So the greatest common factor 234,171 is 9.
Lets's calculate LCM of 19,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 4883
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/4883
Therefore, the GCF of Fractions 234/19,171/257 is 9/4883
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 19,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,257) x common factors =1 x 1 = 1
LCM(19,257) = ( 19 × 257 ) / 1
LCM(19,257) = 4883 / 1
LCM(19,257) = 4883
