Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 345/351,253/362
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 345,253
Greatest Common Factor of Numerators i.e. GCF of 345,253 is 23 .
LCM of Denominators means LCM of 351,362 as per the given fractions.
LCM of 351,362 is 127062 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 345,253
23 | 345, 253 |
15, 11 |
∴ So the GCF of the given numbers is 23 = 23

List of positive integer factors of 345 that divides 345 without a remainder.
1,3,5,15,23,69,115,345
Factors of 253
List of positive integer factors of 253 that divides 253 without a remainder.
1,11,23,253
Greatest Common Factor
We found the factors 345,253 . The biggest common factor number is the GCF number.
So the greatest common factor 345,253 is 23.
Lets's calculate LCM of 351,362
Given numbers has no common factors except 1. So, there LCM is their product i.e 127062
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/127062
Therefore, the GCF of Fractions 345/351,253/362 is 23/127062
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 351,362 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(351,362) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(351,362) x common factors =1 x 1 = 1
LCM(351,362) = ( 351 × 362 ) / 1
LCM(351,362) = 127062 / 1
LCM(351,362) = 127062
Here are some samples of GCF of Fractions calculations.
