Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 393/418,601/517
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 393,601
Greatest Common Factor of Numerators i.e. GCF of 393,601 is 1 .
LCM of Denominators means LCM of 418,517 as per the given fractions.
LCM of 418,517 is 19646 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 393,601
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 393
List of positive integer factors of 393 that divides 393 without a remainder.
1,3,131,393
Factors of 601
List of positive integer factors of 601 that divides 601 without a remainder.
1,601
Greatest Common Factor
We found the factors 393,601 . The biggest common factor number is the GCF number.
So the greatest common factor 393,601 is 1.
Lets's calculate LCM of 418,517
11 | 418, 517 |
38, 47 |
∴ So the LCM of the given numbers is 11 x 38 x 47 = 19646
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19646
Therefore, the GCF of Fractions 393/418,601/517 is 1/19646
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 418,517 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(418,517) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(418,517) x common factors =11 x 1 = 11
LCM(418,517) = ( 418 × 517 ) / 11
LCM(418,517) = 216106 / 11
LCM(418,517) = 19646
