Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 451/69,640/6371
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 451,640
Greatest Common Factor of Numerators i.e. GCF of 451,640 is 1 .
LCM of Denominators means LCM of 69,6371 as per the given fractions.
LCM of 69,6371 is 19113 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 451,640
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
Greatest Common Factor
We found the factors 451,640 . The biggest common factor number is the GCF number.
So the greatest common factor 451,640 is 1.
Lets's calculate LCM of 69,6371
23 | 69, 6371 |
3, 277 |
∴ So the LCM of the given numbers is 23 x 3 x 277 = 19113
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19113
Therefore, the GCF of Fractions 451/69,640/6371 is 1/19113
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 69,6371 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,6371) = 23
common factors(in case of two or more numbers have common factors) = 1
GCF(69,6371) x common factors =23 x 1 = 23
LCM(69,6371) = ( 69 × 6371 ) / 23
LCM(69,6371) = 439599 / 23
LCM(69,6371) = 19113
