Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 5/19,835/80,299/21
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 5,835,299
Greatest Common Factor of Numerators i.e. GCF of 5,835,299 is 1 .
LCM of Denominators means LCM of 19,80,21 as per the given fractions.
LCM of 19,80,21 is 31920 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 5,835,299
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 5
List of positive integer factors of 5 that divides 5 without a remainder.
1,5
Factors of 835
List of positive integer factors of 835 that divides 835 without a remainder.
1,5,167,835
Factors of 299
List of positive integer factors of 299 that divides 299 without a remainder.
1,13,23,299
Greatest Common Factor
We found the factors 5,835,299 . The biggest common factor number is the GCF number.
So the greatest common factor 5,835,299 is 1.
Lets's calculate LCM of 19,80,21
Given numbers has no common factors except 1. So, there LCM is their product i.e 31920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31920
Therefore, the GCF of Fractions 5/19,835/80,299/21 is 1/31920
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 19,80,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,80,21) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,80,21) x common factors =1 x 1 = 1
LCM(19,80,21) = ( 19 × 80 × 21 ) / 1
LCM(19,80,21) = 31920 / 1
LCM(19,80,21) = 31920
Here are some samples of GCF of Fractions calculations.
