Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 72/155,348/806
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 72,348
Greatest Common Factor of Numerators i.e. GCF of 72,348 is 12 .
LCM of Denominators means LCM of 155,806 as per the given fractions.
LCM of 155,806 is 4030 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 72,348
2 | 72, 348 |
2 | 36, 174 |
3 | 18, 87 |
6, 29 |
∴ So the GCF of the given numbers is 2 x 2 x 3 = 12

1,2,3,4,6,12,29,58,87,116,174,348
Greatest Common Factor
We found the factors 72,348 . The biggest common factor number is the GCF number.
So the greatest common factor 72,348 is 12.
Lets's calculate LCM of 155,806
31 | 155, 806 |
5, 26 |
∴ So the LCM of the given numbers is 31 x 5 x 26 = 4030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/4030
Therefore, the GCF of Fractions 72/155,348/806 is 12/4030
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 155,806 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(155,806) = 31
common factors(in case of two or more numbers have common factors) = 1
GCF(155,806) x common factors =31 x 1 = 31
LCM(155,806) = ( 155 × 806 ) / 31
LCM(155,806) = 124930 / 31
LCM(155,806) = 4030
