Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 165/78,145/876
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 165,145
Greatest Common Factor of Numerators i.e. GCF of 165,145 is 5 .
LCM of Denominators means LCM of 78,876 as per the given fractions.
LCM of 78,876 is 11388 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 165,145
5 | 165, 145 |
33, 29 |
∴ So the GCF of the given numbers is 5 = 5

Factors of 145
List of positive integer factors of 145 that divides 145 without a remainder.
1,5,29,145
Greatest Common Factor
We found the factors 165,145 . The biggest common factor number is the GCF number.
So the greatest common factor 165,145 is 5.
Lets's calculate LCM of 78,876
2 | 78, 876 |
3 | 39, 438 |
13, 146 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 146 = 11388
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/11388
Therefore, the GCF of Fractions 165/78,145/876 is 5/11388
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 78,876 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,876) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(78,876) x common factors =6 x 1 = 6
LCM(78,876) = ( 78 × 876 ) / 6
LCM(78,876) = 68328 / 6
LCM(78,876) = 11388
