Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 845/30,215/317
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 845,215
Greatest Common Factor of Numerators i.e. GCF of 845,215 is 5 .
LCM of Denominators means LCM of 30,317 as per the given fractions.
LCM of 30,317 is 9510 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 845,215
5 | 845, 215 |
169, 43 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 845
List of positive integer factors of 845 that divides 845 without a remainder.
1,5,13,65,169,845
Factors of 215
List of positive integer factors of 215 that divides 215 without a remainder.
1,5,43,215
Greatest Common Factor
We found the factors 845,215 . The biggest common factor number is the GCF number.
So the greatest common factor 845,215 is 5.
Lets's calculate LCM of 30,317
Given numbers has no common factors except 1. So, there LCM is their product i.e 9510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/9510
Therefore, the GCF of Fractions 845/30,215/317 is 5/9510
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 30,317 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,317) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(30,317) x common factors =1 x 1 = 1
LCM(30,317) = ( 30 × 317 ) / 1
LCM(30,317) = 9510 / 1
LCM(30,317) = 9510
