Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 2387/84,1540/715
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 2387,1540
Greatest Common Factor of Numerators i.e. GCF of 2387,1540 is 77 .
LCM of Denominators means LCM of 84,715 as per the given fractions.
LCM of 84,715 is 60060 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 2387,1540
7 | 2387, 1540 |
11 | 341, 220 |
31, 20 |
∴ So the GCF of the given numbers is 7 x 11 = 77

Greatest Common Factor
We found the factors 2387,1540 . The biggest common factor number is the GCF number.
So the greatest common factor 2387,1540 is 77.
Lets's calculate LCM of 84,715
Given numbers has no common factors except 1. So, there LCM is their product i.e 60060
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 77/60060
Therefore, the GCF of Fractions 2387/84,1540/715 is 77/60060
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 84,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,715) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(84,715) x common factors =1 x 1 = 1
LCM(84,715) = ( 84 × 715 ) / 1
LCM(84,715) = 60060 / 1
LCM(84,715) = 60060
Here are some samples of GCF of Fractions calculations.
