Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 720/749,172/309
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 720,172
Greatest Common Factor of Numerators i.e. GCF of 720,172 is 4 .
LCM of Denominators means LCM of 749,309 as per the given fractions.
LCM of 749,309 is 231441 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 720,172
2 | 720, 172 |
2 | 360, 86 |
180, 43 |
∴ So the GCF of the given numbers is 2 x 2 = 4

Factors of 172
List of positive integer factors of 172 that divides 172 without a remainder.
1,2,4,43,86,172
Greatest Common Factor
We found the factors 720,172 . The biggest common factor number is the GCF number.
So the greatest common factor 720,172 is 4.
Lets's calculate LCM of 749,309
Given numbers has no common factors except 1. So, there LCM is their product i.e 231441
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/231441
Therefore, the GCF of Fractions 720/749,172/309 is 4/231441
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 749,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(749,309) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(749,309) x common factors =1 x 1 = 1
LCM(749,309) = ( 749 × 309 ) / 1
LCM(749,309) = 231441 / 1
LCM(749,309) = 231441
