Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 34/80,89/90,517/53
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 34,89,517
Greatest Common Factor of Numerators i.e. GCF of 34,89,517 is 1 .
LCM of Denominators means LCM of 80,90,53 as per the given fractions.
LCM of 80,90,53 is 38160 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 34,89,517
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 34
List of positive integer factors of 34 that divides 34 without a remainder.
1,2,17,34

1,89
Factors of 517
List of positive integer factors of 517 that divides 517 without a remainder.
1,11,47,517
Greatest Common Factor
We found the factors 34,89,517 . The biggest common factor number is the GCF number.
So the greatest common factor 34,89,517 is 1.
Lets's calculate LCM of 80,90,53
2 | 80, 90, 53 |
5 | 40, 45, 53 |
8, 9, 53 |
∴ So the LCM of the given numbers is 2 x 5 x 8 x 9 x 53 = 38160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38160
Therefore, the GCF of Fractions 34/80,89/90,517/53 is 1/38160
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 80,90,53 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,90,53) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(80,90,53) x common factors =1 x 10 = 10
LCM(80,90,53) = ( 80 × 90 × 53 ) / 10
LCM(80,90,53) = 381600 / 10
LCM(80,90,53) = 38160
