Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 46/23,20/35,79/68,13/70
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 46,20,79,13
Greatest Common Factor of Numerators i.e. GCF of 46,20,79,13 is 1 .
LCM of Denominators means LCM of 23,35,68,70 as per the given fractions.
LCM of 23,35,68,70 is 54740 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 46,20,79,13
∴ So GCF of numbers is 1 because of no common factors present between them.

1,79
Factors of 13
List of positive integer factors of 13 that divides 13 without a remainder.
1,13
Greatest Common Factor
We found the factors 46,20,79,13 . The biggest common factor number is the GCF number.
So the greatest common factor 46,20,79,13 is 1.
Lets's calculate LCM of 23,35,68,70
2 | 23, 35, 68, 70 |
5 | 23, 35, 34, 35 |
7 | 23, 7, 34, 7 |
23, 1, 34, 1 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 23 x 1 x 34 x 1 = 54740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54740
Therefore, the GCF of Fractions 46/23,20/35,79/68,13/70 is 1/54740
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 23,35,68,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,35,68,70) = 1
common factors(in case of two or more numbers have common factors) = 70
GCF(23,35,68,70) x common factors =1 x 70 = 70
LCM(23,35,68,70) = ( 23 × 35 × 68 × 70 ) / 70
LCM(23,35,68,70) = 3831800 / 70
LCM(23,35,68,70) = 54740
