Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 15/171,540/547
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 15,540
Greatest Common Factor of Numerators i.e. GCF of 15,540 is 15 .
LCM of Denominators means LCM of 171,547 as per the given fractions.
LCM of 171,547 is 93537 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 15,540
3 | 15, 540 |
5 | 5, 180 |
1, 36 |
∴ So the GCF of the given numbers is 3 x 5 = 15
Factors of 15
List of positive integer factors of 15 that divides 15 without a remainder.
1,3,5,15
Factors of 540
List of positive integer factors of 540 that divides 540 without a remainder.
1,2,3,4,5,6,9,10,12,15,18,20,27,30,36,45,54,60,90,108,135,180,270,540
Greatest Common Factor
We found the factors 15,540 . The biggest common factor number is the GCF number.
So the greatest common factor 15,540 is 15.
Lets's calculate LCM of 171,547
Given numbers has no common factors except 1. So, there LCM is their product i.e 93537
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/93537
Therefore, the GCF of Fractions 15/171,540/547 is 15/93537
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 171,547 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(171,547) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(171,547) x common factors =1 x 1 = 1
LCM(171,547) = ( 171 × 547 ) / 1
LCM(171,547) = 93537 / 1
LCM(171,547) = 93537
Here are some samples of GCF of Fractions calculations.
