Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 198/85,378/476
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 198,378
Greatest Common Factor of Numerators i.e. GCF of 198,378 is 18 .
LCM of Denominators means LCM of 85,476 as per the given fractions.
LCM of 85,476 is 2380 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 198,378
2 | 198, 378 |
3 | 99, 189 |
3 | 33, 63 |
11, 21 |
∴ So the GCF of the given numbers is 2 x 3 x 3 = 18

Factors of 378
List of positive integer factors of 378 that divides 378 without a remainder.
1,2,3,6,7,9,14,18,21,27,42,54,63,126,189,378
Greatest Common Factor
We found the factors 198,378 . The biggest common factor number is the GCF number.
So the greatest common factor 198,378 is 18.
Lets's calculate LCM of 85,476
17 | 85, 476 |
5, 28 |
∴ So the LCM of the given numbers is 17 x 5 x 28 = 2380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/2380
Therefore, the GCF of Fractions 198/85,378/476 is 18/2380
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 85,476 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,476) = 17
common factors(in case of two or more numbers have common factors) = 1
GCF(85,476) x common factors =17 x 1 = 17
LCM(85,476) = ( 85 × 476 ) / 17
LCM(85,476) = 40460 / 17
LCM(85,476) = 2380
