Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 9/16,7/71,83/82,15/30
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 9,7,83,15
Greatest Common Factor of Numerators i.e. GCF of 9,7,83,15 is 1 .
LCM of Denominators means LCM of 16,71,82,30 as per the given fractions.
LCM of 16,71,82,30 is 698640 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 9,7,83,15
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 9
List of positive integer factors of 9 that divides 9 without a remainder.
1,3,9
Factors of 7
List of positive integer factors of 7 that divides 7 without a remainder.
1,7
Factors of 83
List of positive integer factors of 83 that divides 83 without a remainder.
1,83
Factors of 15
List of positive integer factors of 15 that divides 15 without a remainder.
1,3,5,15
Greatest Common Factor
We found the factors 9,7,83,15 . The biggest common factor number is the GCF number.
So the greatest common factor 9,7,83,15 is 1.
Lets's calculate LCM of 16,71,82,30
2 | 16, 71, 82, 30 |
8, 71, 41, 15 |
∴ So the LCM of the given numbers is 2 x 8 x 71 x 41 x 15 = 698640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/698640
Therefore, the GCF of Fractions 9/16,7/71,83/82,15/30 is 1/698640
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 16,71,82,30 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,71,82,30) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(16,71,82,30) x common factors =1 x 4 = 4
LCM(16,71,82,30) = ( 16 × 71 × 82 × 30 ) / 4
LCM(16,71,82,30) = 2794560 / 4
LCM(16,71,82,30) = 698640
Here are some samples of GCF of Fractions calculations.
