Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 780/46,180/5205
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 780,180
Greatest Common Factor of Numerators i.e. GCF of 780,180 is 60 .
LCM of Denominators means LCM of 46,5205 as per the given fractions.
LCM of 46,5205 is 239430 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 780,180
2 | 780, 180 |
2 | 390, 90 |
3 | 195, 45 |
5 | 65, 15 |
13, 3 |
∴ So the GCF of the given numbers is 2 x 2 x 3 x 5 = 60

Factors of 180
List of positive integer factors of 180 that divides 180 without a remainder.
1,2,3,4,5,6,9,10,12,15,18,20,30,36,45,60,90,180
Greatest Common Factor
We found the factors 780,180 . The biggest common factor number is the GCF number.
So the greatest common factor 780,180 is 60.
Lets's calculate LCM of 46,5205
Given numbers has no common factors except 1. So, there LCM is their product i.e 239430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 60/239430
Therefore, the GCF of Fractions 780/46,180/5205 is 60/239430
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 46,5205 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(46,5205) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(46,5205) x common factors =1 x 1 = 1
LCM(46,5205) = ( 46 × 5205 ) / 1
LCM(46,5205) = 239430 / 1
LCM(46,5205) = 239430
Here are some samples of GCF of Fractions calculations.
