Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 145/81,380/7345
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 145,380
Greatest Common Factor of Numerators i.e. GCF of 145,380 is 5 .
LCM of Denominators means LCM of 81,7345 as per the given fractions.
LCM of 81,7345 is 594945 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 145,380
5 | 145, 380 |
29, 76 |
∴ So the GCF of the given numbers is 5 = 5

List of positive integer factors of 145 that divides 145 without a remainder.
1,5,29,145
Factors of 380
List of positive integer factors of 380 that divides 380 without a remainder.
1,2,4,5,10,19,20,38,76,95,190,380
Greatest Common Factor
We found the factors 145,380 . The biggest common factor number is the GCF number.
So the greatest common factor 145,380 is 5.
Lets's calculate LCM of 81,7345
Given numbers has no common factors except 1. So, there LCM is their product i.e 594945
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/594945
Therefore, the GCF of Fractions 145/81,380/7345 is 5/594945
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 81,7345 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,7345) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,7345) x common factors =1 x 1 = 1
LCM(81,7345) = ( 81 × 7345 ) / 1
LCM(81,7345) = 594945 / 1
LCM(81,7345) = 594945
Here are some samples of GCF of Fractions calculations.
