Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 81/443,918/724
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 81,918
Greatest Common Factor of Numerators i.e. GCF of 81,918 is 27 .
LCM of Denominators means LCM of 443,724 as per the given fractions.
LCM of 443,724 is 320732 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 81,918
3 | 81, 918 |
3 | 27, 306 |
3 | 9, 102 |
3, 34 |
∴ So the GCF of the given numbers is 3 x 3 x 3 = 27
Factors of 81
List of positive integer factors of 81 that divides 81 without a remainder.
1,3,9,27,81
Factors of 918
List of positive integer factors of 918 that divides 918 without a remainder.
1,2,3,6,9,17,18,27,34,51,54,102,153,306,459,918
Greatest Common Factor
We found the factors 81,918 . The biggest common factor number is the GCF number.
So the greatest common factor 81,918 is 27.
Lets's calculate LCM of 443,724
Given numbers has no common factors except 1. So, there LCM is their product i.e 320732
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/320732
Therefore, the GCF of Fractions 81/443,918/724 is 27/320732
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 443,724 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(443,724) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(443,724) x common factors =1 x 1 = 1
LCM(443,724) = ( 443 × 724 ) / 1
LCM(443,724) = 320732 / 1
LCM(443,724) = 320732
Here are some samples of GCF of Fractions calculations.
