Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 394/289,521/785
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 394,521
Greatest Common Factor of Numerators i.e. GCF of 394,521 is 1 .
LCM of Denominators means LCM of 289,785 as per the given fractions.
LCM of 289,785 is 226865 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 394,521
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 394
List of positive integer factors of 394 that divides 394 without a remainder.
1,2,197,394
Factors of 521
List of positive integer factors of 521 that divides 521 without a remainder.
1,521
Greatest Common Factor
We found the factors 394,521 . The biggest common factor number is the GCF number.
So the greatest common factor 394,521 is 1.
Lets's calculate LCM of 289,785
Given numbers has no common factors except 1. So, there LCM is their product i.e 226865
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/226865
Therefore, the GCF of Fractions 394/289,521/785 is 1/226865
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 289,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(289,785) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(289,785) x common factors =1 x 1 = 1
LCM(289,785) = ( 289 × 785 ) / 1
LCM(289,785) = 226865 / 1
LCM(289,785) = 226865
