Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 225/47,385/9711
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 225,385
Greatest Common Factor of Numerators i.e. GCF of 225,385 is 5 .
LCM of Denominators means LCM of 47,9711 as per the given fractions.
LCM of 47,9711 is 456417 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 225,385
5 | 225, 385 |
45, 77 |
∴ So the GCF of the given numbers is 5 = 5

1,5,7,11,35,55,77,385
Greatest Common Factor
We found the factors 225,385 . The biggest common factor number is the GCF number.
So the greatest common factor 225,385 is 5.
Lets's calculate LCM of 47,9711
Given numbers has no common factors except 1. So, there LCM is their product i.e 456417
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/456417
Therefore, the GCF of Fractions 225/47,385/9711 is 5/456417
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 47,9711 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,9711) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,9711) x common factors =1 x 1 = 1
LCM(47,9711) = ( 47 × 9711 ) / 1
LCM(47,9711) = 456417 / 1
LCM(47,9711) = 456417
Here are some samples of GCF of Fractions calculations.
