Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 46/72,58/91,420/17
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 46,58,420
Greatest Common Factor of Numerators i.e. GCF of 46,58,420 is 2 .
LCM of Denominators means LCM of 72,91,17 as per the given fractions.
LCM of 72,91,17 is 111384 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 46,58,420
2 | 46, 58, 420 |
23, 29, 210 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 420
List of positive integer factors of 420 that divides 420 without a remainder.
1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Greatest Common Factor
We found the factors 46,58,420 . The biggest common factor number is the GCF number.
So the greatest common factor 46,58,420 is 2.
Lets's calculate LCM of 72,91,17
Given numbers has no common factors except 1. So, there LCM is their product i.e 111384
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/111384
Therefore, the GCF of Fractions 46/72,58/91,420/17 is 2/111384
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 72,91,17 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,91,17) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(72,91,17) x common factors =1 x 1 = 1
LCM(72,91,17) = ( 72 × 91 × 17 ) / 1
LCM(72,91,17) = 111384 / 1
LCM(72,91,17) = 111384
Here are some samples of GCF of Fractions calculations.
