Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 1800/92,7840/245
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 1800,7840
Greatest Common Factor of Numerators i.e. GCF of 1800,7840 is 40 .
LCM of Denominators means LCM of 92,245 as per the given fractions.
LCM of 92,245 is 22540 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 1800,7840
2 | 1800, 7840 |
2 | 900, 3920 |
2 | 450, 1960 |
5 | 225, 980 |
45, 196 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 5 = 40

1,2,4,5,7,8,10,14,16,20,28,32,35,40,49,56,70,80,98,112,140,160,196,224,245,280,392,490,560,784,980,1120,1568,1960,3920,7840
Greatest Common Factor
We found the factors 1800,7840 . The biggest common factor number is the GCF number.
So the greatest common factor 1800,7840 is 40.
Lets's calculate LCM of 92,245
Given numbers has no common factors except 1. So, there LCM is their product i.e 22540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 40/22540
Therefore, the GCF of Fractions 1800/92,7840/245 is 40/22540
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 92,245 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(92,245) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(92,245) x common factors =1 x 1 = 1
LCM(92,245) = ( 92 × 245 ) / 1
LCM(92,245) = 22540 / 1
LCM(92,245) = 22540
Here are some samples of GCF of Fractions calculations.
