Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 728/32,847/465
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 728,847
Greatest Common Factor of Numerators i.e. GCF of 728,847 is 7 .
LCM of Denominators means LCM of 32,465 as per the given fractions.
LCM of 32,465 is 14880 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 728,847
7 | 728, 847 |
104, 121 |
∴ So the GCF of the given numbers is 7 = 7

Factors of 847
List of positive integer factors of 847 that divides 847 without a remainder.
1,7,11,77,121,847
Greatest Common Factor
We found the factors 728,847 . The biggest common factor number is the GCF number.
So the greatest common factor 728,847 is 7.
Lets's calculate LCM of 32,465
Given numbers has no common factors except 1. So, there LCM is their product i.e 14880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/14880
Therefore, the GCF of Fractions 728/32,847/465 is 7/14880
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 32,465 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,465) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(32,465) x common factors =1 x 1 = 1
LCM(32,465) = ( 32 × 465 ) / 1
LCM(32,465) = 14880 / 1
LCM(32,465) = 14880
