Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 747/53,690/291
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 747,690
Greatest Common Factor of Numerators i.e. GCF of 747,690 is 3 .
LCM of Denominators means LCM of 53,291 as per the given fractions.
LCM of 53,291 is 15423 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 747,690
3 | 747, 690 |
249, 230 |
∴ So the GCF of the given numbers is 3 = 3

1,2,3,5,6,10,15,23,30,46,69,115,138,230,345,690
Greatest Common Factor
We found the factors 747,690 . The biggest common factor number is the GCF number.
So the greatest common factor 747,690 is 3.
Lets's calculate LCM of 53,291
Given numbers has no common factors except 1. So, there LCM is their product i.e 15423
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/15423
Therefore, the GCF of Fractions 747/53,690/291 is 3/15423
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 53,291 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(53,291) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(53,291) x common factors =1 x 1 = 1
LCM(53,291) = ( 53 × 291 ) / 1
LCM(53,291) = 15423 / 1
LCM(53,291) = 15423
