Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 684/417,738/382
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 684,738
Greatest Common Factor of Numerators i.e. GCF of 684,738 is 18 .
LCM of Denominators means LCM of 417,382 as per the given fractions.
LCM of 417,382 is 159294 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 684,738
2 | 684, 738 |
3 | 342, 369 |
3 | 114, 123 |
38, 41 |
∴ So the GCF of the given numbers is 2 x 3 x 3 = 18

Greatest Common Factor
We found the factors 684,738 . The biggest common factor number is the GCF number.
So the greatest common factor 684,738 is 18.
Lets's calculate LCM of 417,382
Given numbers has no common factors except 1. So, there LCM is their product i.e 159294
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/159294
Therefore, the GCF of Fractions 684/417,738/382 is 18/159294
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 417,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(417,382) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(417,382) x common factors =1 x 1 = 1
LCM(417,382) = ( 417 × 382 ) / 1
LCM(417,382) = 159294 / 1
LCM(417,382) = 159294
Here are some samples of GCF of Fractions calculations.
