Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 387/29,123/1839
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 387,123
Greatest Common Factor of Numerators i.e. GCF of 387,123 is 3 .
LCM of Denominators means LCM of 29,1839 as per the given fractions.
LCM of 29,1839 is 53331 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 387,123
3 | 387, 123 |
129, 41 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 387
List of positive integer factors of 387 that divides 387 without a remainder.
1,3,9,43,129,387
Factors of 123
List of positive integer factors of 123 that divides 123 without a remainder.
1,3,41,123
Greatest Common Factor
We found the factors 387,123 . The biggest common factor number is the GCF number.
So the greatest common factor 387,123 is 3.
Lets's calculate LCM of 29,1839
Given numbers has no common factors except 1. So, there LCM is their product i.e 53331
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/53331
Therefore, the GCF of Fractions 387/29,123/1839 is 3/53331
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 29,1839 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,1839) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(29,1839) x common factors =1 x 1 = 1
LCM(29,1839) = ( 29 × 1839 ) / 1
LCM(29,1839) = 53331 / 1
LCM(29,1839) = 53331
