Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 18/299,50/821
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 18,50
Greatest Common Factor of Numerators i.e. GCF of 18,50 is 2 .
LCM of Denominators means LCM of 299,821 as per the given fractions.
LCM of 299,821 is 245479 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 18,50
2 | 18, 50 |
9, 25 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 18
List of positive integer factors of 18 that divides 18 without a remainder.
1,2,3,6,9,18
Factors of 50
List of positive integer factors of 50 that divides 50 without a remainder.
1,2,5,10,25,50
Greatest Common Factor
We found the factors 18,50 . The biggest common factor number is the GCF number.
So the greatest common factor 18,50 is 2.
Lets's calculate LCM of 299,821
Given numbers has no common factors except 1. So, there LCM is their product i.e 245479
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/245479
Therefore, the GCF of Fractions 18/299,50/821 is 2/245479
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 299,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(299,821) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(299,821) x common factors =1 x 1 = 1
LCM(299,821) = ( 299 × 821 ) / 1
LCM(299,821) = 245479 / 1
LCM(299,821) = 245479
Here are some samples of GCF of Fractions calculations.
