Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 28/71,74/75,12/662
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 28,74,12
Greatest Common Factor of Numerators i.e. GCF of 28,74,12 is 2 .
LCM of Denominators means LCM of 71,75,662 as per the given fractions.
LCM of 71,75,662 is 3525150 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 28,74,12
2 | 28, 74, 12 |
14, 37, 6 |
∴ So the GCF of the given numbers is 2 = 2

1,2,4,7,14,28
Factors of 74
List of positive integer factors of 74 that divides 74 without a remainder.
1,2,37,74
Factors of 12
List of positive integer factors of 12 that divides 12 without a remainder.
1,2,3,4,6,12
Greatest Common Factor
We found the factors 28,74,12 . The biggest common factor number is the GCF number.
So the greatest common factor 28,74,12 is 2.
Lets's calculate LCM of 71,75,662
Given numbers has no common factors except 1. So, there LCM is their product i.e 3525150
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3525150
Therefore, the GCF of Fractions 28/71,74/75,12/662 is 2/3525150
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 71,75,662 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,75,662) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,75,662) x common factors =1 x 1 = 1
LCM(71,75,662) = ( 71 × 75 × 662 ) / 1
LCM(71,75,662) = 3525150 / 1
LCM(71,75,662) = 3525150
Here are some samples of GCF of Fractions calculations.
