Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 946/485,178/251
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 946,178
Greatest Common Factor of Numerators i.e. GCF of 946,178 is 2 .
LCM of Denominators means LCM of 485,251 as per the given fractions.
LCM of 485,251 is 121735 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 946,178
2 | 946, 178 |

Factors of 178
List of positive integer factors of 178 that divides 178 without a remainder.
1,2,89,178
Greatest Common Factor
We found the factors 946,178 . The biggest common factor number is the GCF number.
So the greatest common factor 946,178 is 2.
Lets's calculate LCM of 485,251
Given numbers has no common factors except 1. So, there LCM is their product i.e 121735
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/121735
Therefore, the GCF of Fractions 946/485,178/251 is 2/121735
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 485,251 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(485,251) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(485,251) x common factors =1 x 1 = 1
LCM(485,251) = ( 485 × 251 ) / 1
LCM(485,251) = 121735 / 1
LCM(485,251) = 121735
