Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 43/801,640/990
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 43,640
Greatest Common Factor of Numerators i.e. GCF of 43,640 is 1 .
LCM of Denominators means LCM of 801,990 as per the given fractions.
LCM of 801,990 is 88110 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 43,640
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 43 that divides 43 without a remainder.
1,43
Factors of 640
List of positive integer factors of 640 that divides 640 without a remainder.
1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
Greatest Common Factor
We found the factors 43,640 . The biggest common factor number is the GCF number.
So the greatest common factor 43,640 is 1.
Lets's calculate LCM of 801,990
3 | 801, 990 |
3 | 267, 330 |
89, 110 |
∴ So the LCM of the given numbers is 3 x 3 x 89 x 110 = 88110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/88110
Therefore, the GCF of Fractions 43/801,640/990 is 1/88110
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 801,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(801,990) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(801,990) x common factors =9 x 1 = 9
LCM(801,990) = ( 801 × 990 ) / 9
LCM(801,990) = 792990 / 9
LCM(801,990) = 88110
