Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 985/57,643/6851
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 985,643
Greatest Common Factor of Numerators i.e. GCF of 985,643 is 1 .
LCM of Denominators means LCM of 57,6851 as per the given fractions.
LCM of 57,6851 is 390507 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 985,643
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 985
List of positive integer factors of 985 that divides 985 without a remainder.
1,5,197,985
Factors of 643
List of positive integer factors of 643 that divides 643 without a remainder.
1,643
Greatest Common Factor
We found the factors 985,643 . The biggest common factor number is the GCF number.
So the greatest common factor 985,643 is 1.
Lets's calculate LCM of 57,6851
Given numbers has no common factors except 1. So, there LCM is their product i.e 390507
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/390507
Therefore, the GCF of Fractions 985/57,643/6851 is 1/390507
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 57,6851 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,6851) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(57,6851) x common factors =1 x 1 = 1
LCM(57,6851) = ( 57 × 6851 ) / 1
LCM(57,6851) = 390507 / 1
LCM(57,6851) = 390507
