Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 14/420,291/305
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 14,291
Greatest Common Factor of Numerators i.e. GCF of 14,291 is 1 .
LCM of Denominators means LCM of 420,305 as per the given fractions.
LCM of 420,305 is 25620 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 14,291
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 14
List of positive integer factors of 14 that divides 14 without a remainder.
1,2,7,14
Factors of 291
List of positive integer factors of 291 that divides 291 without a remainder.
1,3,97,291
Greatest Common Factor
We found the factors 14,291 . The biggest common factor number is the GCF number.
So the greatest common factor 14,291 is 1.
Lets's calculate LCM of 420,305
5 | 420, 305 |
84, 61 |
∴ So the LCM of the given numbers is 5 x 84 x 61 = 25620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25620
Therefore, the GCF of Fractions 14/420,291/305 is 1/25620
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 420,305 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,305) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(420,305) x common factors =5 x 1 = 5
LCM(420,305) = ( 420 × 305 ) / 5
LCM(420,305) = 128100 / 5
LCM(420,305) = 25620
