Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 189/321,2097/445
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 189,2097
Greatest Common Factor of Numerators i.e. GCF of 189,2097 is 9 .
LCM of Denominators means LCM of 321,445 as per the given fractions.
LCM of 321,445 is 142845 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 189,2097
3 | 189, 2097 |
3 | 63, 699 |
21, 233 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Factors of 189
List of positive integer factors of 189 that divides 189 without a remainder.
1,3,7,9,21,27,63,189
Factors of 2097
List of positive integer factors of 2097 that divides 2097 without a remainder.
1,3,9,233,699,2097
Greatest Common Factor
We found the factors 189,2097 . The biggest common factor number is the GCF number.
So the greatest common factor 189,2097 is 9.
Lets's calculate LCM of 321,445
Given numbers has no common factors except 1. So, there LCM is their product i.e 142845
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/142845
Therefore, the GCF of Fractions 189/321,2097/445 is 9/142845
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 321,445 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(321,445) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(321,445) x common factors =1 x 1 = 1
LCM(321,445) = ( 321 × 445 ) / 1
LCM(321,445) = 142845 / 1
LCM(321,445) = 142845
Here are some samples of GCF of Fractions calculations.
