Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 11/20,12/60,76/10,52/85
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 11,12,76,52
Greatest Common Factor of Numerators i.e. GCF of 11,12,76,52 is 1 .
LCM of Denominators means LCM of 20,60,10,85 as per the given fractions.
LCM of 20,60,10,85 is 1020 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 11,12,76,52
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,3,4,6,12
Factors of 76
List of positive integer factors of 76 that divides 76 without a remainder.
1,2,4,19,38,76
Factors of 52
List of positive integer factors of 52 that divides 52 without a remainder.
1,2,4,13,26,52
Greatest Common Factor
We found the factors 11,12,76,52 . The biggest common factor number is the GCF number.
So the greatest common factor 11,12,76,52 is 1.
Lets's calculate LCM of 20,60,10,85
2 | 20, 60, 10, 85 |
2 | 10, 30, 5, 85 |
5 | 5, 15, 5, 85 |
1, 3, 1, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 3 x 1 x 17 = 1020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1020
Therefore, the GCF of Fractions 11/20,12/60,76/10,52/85 is 1/1020
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 20,60,10,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,60,10,85) = 5
common factors(in case of two or more numbers have common factors) = 200
GCF(20,60,10,85) x common factors =5 x 200 = 1000
LCM(20,60,10,85) = ( 20 × 60 × 10 × 85 ) / 1000
LCM(20,60,10,85) = 1020000 / 1000
LCM(20,60,10,85) = 1020
