Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 490/618,413/294
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 490,413
Greatest Common Factor of Numerators i.e. GCF of 490,413 is 7 .
LCM of Denominators means LCM of 618,294 as per the given fractions.
LCM of 618,294 is 30282 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 490,413
7 | 490, 413 |
70, 59 |
∴ So the GCF of the given numbers is 7 = 7

Factors of 413
List of positive integer factors of 413 that divides 413 without a remainder.
1,7,59,413
Greatest Common Factor
We found the factors 490,413 . The biggest common factor number is the GCF number.
So the greatest common factor 490,413 is 7.
Lets's calculate LCM of 618,294
2 | 618, 294 |
3 | 309, 147 |
103, 49 |
∴ So the LCM of the given numbers is 2 x 3 x 103 x 49 = 30282
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/30282
Therefore, the GCF of Fractions 490/618,413/294 is 7/30282
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 618,294 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(618,294) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(618,294) x common factors =6 x 1 = 6
LCM(618,294) = ( 618 × 294 ) / 6
LCM(618,294) = 181692 / 6
LCM(618,294) = 30282
