Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 217/848,415/556
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 217,415
Greatest Common Factor of Numerators i.e. GCF of 217,415 is 1 .
LCM of Denominators means LCM of 848,556 as per the given fractions.
LCM of 848,556 is 117872 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 217,415
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 217
List of positive integer factors of 217 that divides 217 without a remainder.
1,7,31,217
Factors of 415
List of positive integer factors of 415 that divides 415 without a remainder.
1,5,83,415
Greatest Common Factor
We found the factors 217,415 . The biggest common factor number is the GCF number.
So the greatest common factor 217,415 is 1.
Lets's calculate LCM of 848,556
2 | 848, 556 |
2 | 424, 278 |
212, 139 |
∴ So the LCM of the given numbers is 2 x 2 x 212 x 139 = 117872
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/117872
Therefore, the GCF of Fractions 217/848,415/556 is 1/117872
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 848,556 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(848,556) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(848,556) x common factors =4 x 1 = 4
LCM(848,556) = ( 848 × 556 ) / 4
LCM(848,556) = 471488 / 4
LCM(848,556) = 117872
