Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 318/702,1117/689
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 318,1117
Greatest Common Factor of Numerators i.e. GCF of 318,1117 is 1 .
LCM of Denominators means LCM of 702,689 as per the given fractions.
LCM of 702,689 is 37206 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 318,1117
∴ So GCF of numbers is 1 because of no common factors present between them.

Factors of 1117
List of positive integer factors of 1117 that divides 1117 without a remainder.
1,1117
Greatest Common Factor
We found the factors 318,1117 . The biggest common factor number is the GCF number.
So the greatest common factor 318,1117 is 1.
Lets's calculate LCM of 702,689
13 | 702, 689 |
54, 53 |
∴ So the LCM of the given numbers is 13 x 54 x 53 = 37206
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/37206
Therefore, the GCF of Fractions 318/702,1117/689 is 1/37206
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 702,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(702,689) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(702,689) x common factors =13 x 1 = 13
LCM(702,689) = ( 702 × 689 ) / 13
LCM(702,689) = 483678 / 13
LCM(702,689) = 37206
