Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 381/472,258/703
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 381,258
Greatest Common Factor of Numerators i.e. GCF of 381,258 is 3 .
LCM of Denominators means LCM of 472,703 as per the given fractions.
LCM of 472,703 is 331816 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 381,258
3 | 381, 258 |
127, 86 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 381
List of positive integer factors of 381 that divides 381 without a remainder.
1,3,127,381
Factors of 258
List of positive integer factors of 258 that divides 258 without a remainder.
1,2,3,6,43,86,129,258
Greatest Common Factor
We found the factors 381,258 . The biggest common factor number is the GCF number.
So the greatest common factor 381,258 is 3.
Lets's calculate LCM of 472,703
Given numbers has no common factors except 1. So, there LCM is their product i.e 331816
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/331816
Therefore, the GCF of Fractions 381/472,258/703 is 3/331816
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 472,703 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(472,703) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(472,703) x common factors =1 x 1 = 1
LCM(472,703) = ( 472 × 703 ) / 1
LCM(472,703) = 331816 / 1
LCM(472,703) = 331816
Here are some samples of GCF of Fractions calculations.
