Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 2923/451,1591/393
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 2923,1591
Greatest Common Factor of Numerators i.e. GCF of 2923,1591 is 37 .
LCM of Denominators means LCM of 451,393 as per the given fractions.
LCM of 451,393 is 177243 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 2923,1591
37 | 2923, 1591 |
79, 43 |
∴ So the GCF of the given numbers is 37 = 37
Factors of 2923
List of positive integer factors of 2923 that divides 2923 without a remainder.
1,37,79,2923
Factors of 1591
List of positive integer factors of 1591 that divides 1591 without a remainder.
1,37,43,1591
Greatest Common Factor
We found the factors 2923,1591 . The biggest common factor number is the GCF number.
So the greatest common factor 2923,1591 is 37.
Lets's calculate LCM of 451,393
Given numbers has no common factors except 1. So, there LCM is their product i.e 177243
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 37/177243
Therefore, the GCF of Fractions 2923/451,1591/393 is 37/177243
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 451,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(451,393) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(451,393) x common factors =1 x 1 = 1
LCM(451,393) = ( 451 × 393 ) / 1
LCM(451,393) = 177243 / 1
LCM(451,393) = 177243
Here are some samples of GCF of Fractions calculations.
