Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 17/38,11/74,986/78
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 17,11,986
Greatest Common Factor of Numerators i.e. GCF of 17,11,986 is 1 .
LCM of Denominators means LCM of 38,74,78 as per the given fractions.
LCM of 38,74,78 is 54834 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 17,11,986
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 17

1,17
Factors of 11
List of positive integer factors of 11 that divides 11 without a remainder.
1,11
Factors of 986
List of positive integer factors of 986 that divides 986 without a remainder.
1,2,17,29,34,58,493,986
Greatest Common Factor
We found the factors 17,11,986 . The biggest common factor number is the GCF number.
So the greatest common factor 17,11,986 is 1.
Lets's calculate LCM of 38,74,78
2 | 38, 74, 78 |
19, 37, 39 |
∴ So the LCM of the given numbers is 2 x 19 x 37 x 39 = 54834
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54834
Therefore, the GCF of Fractions 17/38,11/74,986/78 is 1/54834
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 38,74,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,74,78) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(38,74,78) x common factors =2 x 2 = 4
LCM(38,74,78) = ( 38 × 74 × 78 ) / 4
LCM(38,74,78) = 219336 / 4
LCM(38,74,78) = 54834
