Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 391/6004,989/4002
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 391,989
Greatest Common Factor of Numerators i.e. GCF of 391,989 is 23 .
LCM of Denominators means LCM of 6004,4002 as per the given fractions.
LCM of 6004,4002 is 12014004 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 391,989
23 | 391, 989 |
17, 43 |
∴ So the GCF of the given numbers is 23 = 23
Factors of 391

Factors of 989
List of positive integer factors of 989 that divides 989 without a remainder.
1,23,43,989
Greatest Common Factor
We found the factors 391,989 . The biggest common factor number is the GCF number.
So the greatest common factor 391,989 is 23.
Lets's calculate LCM of 6004,4002
2 | 6004, 4002 |
3002, 2001 |
∴ So the LCM of the given numbers is 2 x 3002 x 2001 = 12014004
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/12014004
Therefore, the GCF of Fractions 391/6004,989/4002 is 23/12014004
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 6004,4002 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(6004,4002) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(6004,4002) x common factors =2 x 1 = 2
LCM(6004,4002) = ( 6004 × 4002 ) / 2
LCM(6004,4002) = 24028008 / 2
LCM(6004,4002) = 12014004
