Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 5/403,81/217,99/847
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 5,81,99
Greatest Common Factor of Numerators i.e. GCF of 5,81,99 is 1 .
LCM of Denominators means LCM of 403,217,847 as per the given fractions.
LCM of 403,217,847 is 341341 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 5,81,99
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 5
List of positive integer factors of 5 that divides 5 without a remainder.
1,5
Factors of 81
List of positive integer factors of 81 that divides 81 without a remainder.
1,3,9,27,81
Factors of 99
List of positive integer factors of 99 that divides 99 without a remainder.
1,3,9,11,33,99
Greatest Common Factor
We found the factors 5,81,99 . The biggest common factor number is the GCF number.
So the greatest common factor 5,81,99 is 1.
Lets's calculate LCM of 403,217,847
7 | 403, 217, 847 |
31 | 403, 31, 121 |
13, 1, 121 |
∴ So the LCM of the given numbers is 7 x 31 x 13 x 1 x 121 = 341341
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/341341
Therefore, the GCF of Fractions 5/403,81/217,99/847 is 1/341341
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 403,217,847 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(403,217,847) = 1
common factors(in case of two or more numbers have common factors) = 217
GCF(403,217,847) x common factors =1 x 217 = 217
LCM(403,217,847) = ( 403 × 217 × 847 ) / 217
LCM(403,217,847) = 74070997 / 217
LCM(403,217,847) = 341341
