Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 80/291,647/417
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 80,647
Greatest Common Factor of Numerators i.e. GCF of 80,647 is 1 .
LCM of Denominators means LCM of 291,417 as per the given fractions.
LCM of 291,417 is 40449 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 80,647
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 80
List of positive integer factors of 80 that divides 80 without a remainder.
1,2,4,5,8,10,16,20,40,80
Factors of 647
List of positive integer factors of 647 that divides 647 without a remainder.
1,647
Greatest Common Factor
We found the factors 80,647 . The biggest common factor number is the GCF number.
So the greatest common factor 80,647 is 1.
Lets's calculate LCM of 291,417
3 | 291, 417 |
97, 139 |
∴ So the LCM of the given numbers is 3 x 97 x 139 = 40449
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/40449
Therefore, the GCF of Fractions 80/291,647/417 is 1/40449
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 291,417 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(291,417) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(291,417) x common factors =3 x 1 = 3
LCM(291,417) = ( 291 × 417 ) / 3
LCM(291,417) = 121347 / 3
LCM(291,417) = 40449
