Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 790/80,850/646
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 790,850
Greatest Common Factor of Numerators i.e. GCF of 790,850 is 10 .
LCM of Denominators means LCM of 80,646 as per the given fractions.
LCM of 80,646 is 25840 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 790,850
2 | 790, 850 |
5 | 395, 425 |
79, 85 |
∴ So the GCF of the given numbers is 2 x 5 = 10

1,2,5,10,17,25,34,50,85,170,425,850
Greatest Common Factor
We found the factors 790,850 . The biggest common factor number is the GCF number.
So the greatest common factor 790,850 is 10.
Lets's calculate LCM of 80,646
2 | 80, 646 |
40, 323 |
∴ So the LCM of the given numbers is 2 x 40 x 323 = 25840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/25840
Therefore, the GCF of Fractions 790/80,850/646 is 10/25840
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 80,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,646) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(80,646) x common factors =2 x 1 = 2
LCM(80,646) = ( 80 × 646 ) / 2
LCM(80,646) = 51680 / 2
LCM(80,646) = 25840
