Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 19/73,72/13,801/18
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 19,72,801
Greatest Common Factor of Numerators i.e. GCF of 19,72,801 is 1 .
LCM of Denominators means LCM of 73,13,18 as per the given fractions.
LCM of 73,13,18 is 17082 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 19,72,801
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 19
List of positive integer factors of 19 that divides 19 without a remainder.
1,19
Factors of 72
List of positive integer factors of 72 that divides 72 without a remainder.
1,2,3,4,6,8,9,12,18,24,36,72
Factors of 801
List of positive integer factors of 801 that divides 801 without a remainder.
1,3,9,89,267,801
Greatest Common Factor
We found the factors 19,72,801 . The biggest common factor number is the GCF number.
So the greatest common factor 19,72,801 is 1.
Lets's calculate LCM of 73,13,18
Given numbers has no common factors except 1. So, there LCM is their product i.e 17082
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17082
Therefore, the GCF of Fractions 19/73,72/13,801/18 is 1/17082
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 73,13,18 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,13,18) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(73,13,18) x common factors =1 x 1 = 1
LCM(73,13,18) = ( 73 × 13 × 18 ) / 1
LCM(73,13,18) = 17082 / 1
LCM(73,13,18) = 17082
Here are some samples of GCF of Fractions calculations.
