Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 1/13,205/91,363/91
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 1,205,363
Greatest Common Factor of Numerators i.e. GCF of 1,205,363 is 1 .
LCM of Denominators means LCM of 13,91,91 as per the given fractions.
LCM of 13,91,91 is 91 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 1,205,363
∴ So GCF of numbers is 1 because of no common factors present between them.

1
Factors of 205
List of positive integer factors of 205 that divides 205 without a remainder.
1,5,41,205
Factors of 363
List of positive integer factors of 363 that divides 363 without a remainder.
1,3,11,33,121,363
Greatest Common Factor
We found the factors 1,205,363 . The biggest common factor number is the GCF number.
So the greatest common factor 1,205,363 is 1.
Lets's calculate LCM of 13,91,91
7 | 13, 91, 91 |
13 | 13, 13, 13 |
1, 1, 1 |
∴ So the LCM of the given numbers is 7 x 13 x 1 x 1 x 1 = 91
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/91
Therefore, the GCF of Fractions 1/13,205/91,363/91 is 1/91
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 13,91,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,91,91) = 13
common factors(in case of two or more numbers have common factors) = 91
GCF(13,91,91) x common factors =13 x 91 = 1183
LCM(13,91,91) = ( 13 × 91 × 91 ) / 1183
LCM(13,91,91) = 107653 / 1183
LCM(13,91,91) = 91
