Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 1205/78,3418/325
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 1205,3418
Greatest Common Factor of Numerators i.e. GCF of 1205,3418 is 1 .
LCM of Denominators means LCM of 78,325 as per the given fractions.
LCM of 78,325 is 1950 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 1205,3418
∴ So GCF of numbers is 1 because of no common factors present between them.

1,5,241,1205
Factors of 3418
List of positive integer factors of 3418 that divides 3418 without a remainder.
1,2,1709,3418
Greatest Common Factor
We found the factors 1205,3418 . The biggest common factor number is the GCF number.
So the greatest common factor 1205,3418 is 1.
Lets's calculate LCM of 78,325
13 | 78, 325 |
6, 25 |
∴ So the LCM of the given numbers is 13 x 6 x 25 = 1950
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1950
Therefore, the GCF of Fractions 1205/78,3418/325 is 1/1950
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 78,325 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,325) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(78,325) x common factors =13 x 1 = 13
LCM(78,325) = ( 78 × 325 ) / 13
LCM(78,325) = 25350 / 13
LCM(78,325) = 1950
