Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 209/734,143/555
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 209,143
Greatest Common Factor of Numerators i.e. GCF of 209,143 is 11 .
LCM of Denominators means LCM of 734,555 as per the given fractions.
LCM of 734,555 is 407370 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 209,143
11 | 209, 143 |
19, 13 |
∴ So the GCF of the given numbers is 11 = 11
Factors of 209
List of positive integer factors of 209 that divides 209 without a remainder.
1,11,19,209
Factors of 143
List of positive integer factors of 143 that divides 143 without a remainder.
1,11,13,143
Greatest Common Factor
We found the factors 209,143 . The biggest common factor number is the GCF number.
So the greatest common factor 209,143 is 11.
Lets's calculate LCM of 734,555
Given numbers has no common factors except 1. So, there LCM is their product i.e 407370
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/407370
Therefore, the GCF of Fractions 209/734,143/555 is 11/407370
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 734,555 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(734,555) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(734,555) x common factors =1 x 1 = 1
LCM(734,555) = ( 734 × 555 ) / 1
LCM(734,555) = 407370 / 1
LCM(734,555) = 407370
Here are some samples of GCF of Fractions calculations.
