Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 870/21,790/4015
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 870,790
Greatest Common Factor of Numerators i.e. GCF of 870,790 is 10 .
LCM of Denominators means LCM of 21,4015 as per the given fractions.
LCM of 21,4015 is 84315 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 870,790
2 | 870, 790 |
5 | 435, 395 |
87, 79 |
∴ So the GCF of the given numbers is 2 x 5 = 10

Factors of 790
List of positive integer factors of 790 that divides 790 without a remainder.
1,2,5,10,79,158,395,790
Greatest Common Factor
We found the factors 870,790 . The biggest common factor number is the GCF number.
So the greatest common factor 870,790 is 10.
Lets's calculate LCM of 21,4015
Given numbers has no common factors except 1. So, there LCM is their product i.e 84315
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/84315
Therefore, the GCF of Fractions 870/21,790/4015 is 10/84315
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 21,4015 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,4015) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,4015) x common factors =1 x 1 = 1
LCM(21,4015) = ( 21 × 4015 ) / 1
LCM(21,4015) = 84315 / 1
LCM(21,4015) = 84315
Here are some samples of GCF of Fractions calculations.
