Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 518/847,530/398
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 518,530
Greatest Common Factor of Numerators i.e. GCF of 518,530 is 2 .
LCM of Denominators means LCM of 847,398 as per the given fractions.
LCM of 847,398 is 337106 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 518,530
2 | 518, 530 |
259, 265 |
∴ So the GCF of the given numbers is 2 = 2

1,2,7,14,37,74,259,518
Factors of 530
List of positive integer factors of 530 that divides 530 without a remainder.
1,2,5,10,53,106,265,530
Greatest Common Factor
We found the factors 518,530 . The biggest common factor number is the GCF number.
So the greatest common factor 518,530 is 2.
Lets's calculate LCM of 847,398
Given numbers has no common factors except 1. So, there LCM is their product i.e 337106
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/337106
Therefore, the GCF of Fractions 518/847,530/398 is 2/337106
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 847,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(847,398) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(847,398) x common factors =1 x 1 = 1
LCM(847,398) = ( 847 × 398 ) / 1
LCM(847,398) = 337106 / 1
LCM(847,398) = 337106
Here are some samples of GCF of Fractions calculations.
