Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 82/28,26/71,238/650
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 82,26,238
Greatest Common Factor of Numerators i.e. GCF of 82,26,238 is 2 .
LCM of Denominators means LCM of 28,71,650 as per the given fractions.
LCM of 28,71,650 is 646100 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 82,26,238
2 | 82, 26, 238 |
41, 13, 119 |
∴ So the GCF of the given numbers is 2 = 2

1,2,7,14,17,34,119,238
Greatest Common Factor
We found the factors 82,26,238 . The biggest common factor number is the GCF number.
So the greatest common factor 82,26,238 is 2.
Lets's calculate LCM of 28,71,650
2 | 28, 71, 650 |
14, 71, 325 |
∴ So the LCM of the given numbers is 2 x 14 x 71 x 325 = 646100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/646100
Therefore, the GCF of Fractions 82/28,26/71,238/650 is 2/646100
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 28,71,650 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,71,650) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(28,71,650) x common factors =1 x 2 = 2
LCM(28,71,650) = ( 28 × 71 × 650 ) / 2
LCM(28,71,650) = 1292200 / 2
LCM(28,71,650) = 646100
