Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 13/26,85/79,23/64,65/15
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 13,85,23,65
Greatest Common Factor of Numerators i.e. GCF of 13,85,23,65 is 1 .
LCM of Denominators means LCM of 26,79,64,15 as per the given fractions.
LCM of 26,79,64,15 is 985920 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 13,85,23,65
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 13

Greatest Common Factor
We found the factors 13,85,23,65 . The biggest common factor number is the GCF number.
So the greatest common factor 13,85,23,65 is 1.
Lets's calculate LCM of 26,79,64,15
2 | 26, 79, 64, 15 |
13, 79, 32, 15 |
∴ So the LCM of the given numbers is 2 x 13 x 79 x 32 x 15 = 985920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/985920
Therefore, the GCF of Fractions 13/26,85/79,23/64,65/15 is 1/985920
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 26,79,64,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,79,64,15) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(26,79,64,15) x common factors =1 x 2 = 2
LCM(26,79,64,15) = ( 26 × 79 × 64 × 15 ) / 2
LCM(26,79,64,15) = 1971840 / 2
LCM(26,79,64,15) = 985920
