Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 258/231,621/166
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 258,621
Greatest Common Factor of Numerators i.e. GCF of 258,621 is 3 .
LCM of Denominators means LCM of 231,166 as per the given fractions.
LCM of 231,166 is 38346 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 258,621
3 | 258, 621 |
86, 207 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 258
List of positive integer factors of 258 that divides 258 without a remainder.
1,2,3,6,43,86,129,258
Factors of 621
List of positive integer factors of 621 that divides 621 without a remainder.
1,3,9,23,27,69,207,621
Greatest Common Factor
We found the factors 258,621 . The biggest common factor number is the GCF number.
So the greatest common factor 258,621 is 3.
Lets's calculate LCM of 231,166
Given numbers has no common factors except 1. So, there LCM is their product i.e 38346
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/38346
Therefore, the GCF of Fractions 258/231,621/166 is 3/38346
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 231,166 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(231,166) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(231,166) x common factors =1 x 1 = 1
LCM(231,166) = ( 231 × 166 ) / 1
LCM(231,166) = 38346 / 1
LCM(231,166) = 38346
Here are some samples of GCF of Fractions calculations.
