Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 836/39,456/985
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 836,456
Greatest Common Factor of Numerators i.e. GCF of 836,456 is 76 .
LCM of Denominators means LCM of 39,985 as per the given fractions.
LCM of 39,985 is 38415 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 836,456
2 | 836, 456 |
2 | 418, 228 |
19 | 209, 114 |
11, 6 |
∴ So the GCF of the given numbers is 2 x 2 x 19 = 76

Greatest Common Factor
We found the factors 836,456 . The biggest common factor number is the GCF number.
So the greatest common factor 836,456 is 76.
Lets's calculate LCM of 39,985
Given numbers has no common factors except 1. So, there LCM is their product i.e 38415
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 76/38415
Therefore, the GCF of Fractions 836/39,456/985 is 76/38415
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 39,985 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,985) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,985) x common factors =1 x 1 = 1
LCM(39,985) = ( 39 × 985 ) / 1
LCM(39,985) = 38415 / 1
LCM(39,985) = 38415
Here are some samples of GCF of Fractions calculations.
