Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 68/398,14/9228
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 68,14
Greatest Common Factor of Numerators i.e. GCF of 68,14 is 2 .
LCM of Denominators means LCM of 398,9228 as per the given fractions.
LCM of 398,9228 is 1836372 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 68,14
2 | 68, 14 |
34, 7 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 68
List of positive integer factors of 68 that divides 68 without a remainder.
1,2,4,17,34,68
Factors of 14
List of positive integer factors of 14 that divides 14 without a remainder.
1,2,7,14
Greatest Common Factor
We found the factors 68,14 . The biggest common factor number is the GCF number.
So the greatest common factor 68,14 is 2.
Lets's calculate LCM of 398,9228
2 | 398, 9228 |
199, 4614 |
∴ So the LCM of the given numbers is 2 x 199 x 4614 = 1836372
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1836372
Therefore, the GCF of Fractions 68/398,14/9228 is 2/1836372
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 398,9228 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,9228) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(398,9228) x common factors =2 x 1 = 2
LCM(398,9228) = ( 398 × 9228 ) / 2
LCM(398,9228) = 3672744 / 2
LCM(398,9228) = 1836372
