Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 3/961,8/639
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 3,8
Greatest Common Factor of Numerators i.e. GCF of 3,8 is 1 .
LCM of Denominators means LCM of 961,639 as per the given fractions.
LCM of 961,639 is 614079 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 3,8
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 3
List of positive integer factors of 3 that divides 3 without a remainder.
1,3
Factors of 8
List of positive integer factors of 8 that divides 8 without a remainder.
1,2,4,8
Greatest Common Factor
We found the factors 3,8 . The biggest common factor number is the GCF number.
So the greatest common factor 3,8 is 1.
Lets's calculate LCM of 961,639
Given numbers has no common factors except 1. So, there LCM is their product i.e 614079
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/614079
Therefore, the GCF of Fractions 3/961,8/639 is 1/614079
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 961,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(961,639) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(961,639) x common factors =1 x 1 = 1
LCM(961,639) = ( 961 × 639 ) / 1
LCM(961,639) = 614079 / 1
LCM(961,639) = 614079
Here are some samples of GCF of Fractions calculations.
