Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 4/79,280/34,564/35
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 4,280,564
Greatest Common Factor of Numerators i.e. GCF of 4,280,564 is 4 .
LCM of Denominators means LCM of 79,34,35 as per the given fractions.
LCM of 79,34,35 is 94010 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 4,280,564
2 | 4, 280, 564 |
2 | 2, 140, 282 |
1, 70, 141 |
∴ So the GCF of the given numbers is 2 x 2 = 4

1,2,4,5,7,8,10,14,20,28,35,40,56,70,140,280
Factors of 564
List of positive integer factors of 564 that divides 564 without a remainder.
1,2,3,4,6,12,47,94,141,188,282,564
Greatest Common Factor
We found the factors 4,280,564 . The biggest common factor number is the GCF number.
So the greatest common factor 4,280,564 is 4.
Lets's calculate LCM of 79,34,35
Given numbers has no common factors except 1. So, there LCM is their product i.e 94010
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/94010
Therefore, the GCF of Fractions 4/79,280/34,564/35 is 4/94010
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 79,34,35 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,34,35) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,34,35) x common factors =1 x 1 = 1
LCM(79,34,35) = ( 79 × 34 × 35 ) / 1
LCM(79,34,35) = 94010 / 1
LCM(79,34,35) = 94010
Here are some samples of GCF of Fractions calculations.
