Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 723/172,181/989
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 723,181
Greatest Common Factor of Numerators i.e. GCF of 723,181 is 1 .
LCM of Denominators means LCM of 172,989 as per the given fractions.
LCM of 172,989 is 3956 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 723,181
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 723
List of positive integer factors of 723 that divides 723 without a remainder.
1,3,241,723
Factors of 181
List of positive integer factors of 181 that divides 181 without a remainder.
1,181
Greatest Common Factor
We found the factors 723,181 . The biggest common factor number is the GCF number.
So the greatest common factor 723,181 is 1.
Lets's calculate LCM of 172,989
43 | 172, 989 |
4, 23 |
∴ So the LCM of the given numbers is 43 x 4 x 23 = 3956
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3956
Therefore, the GCF of Fractions 723/172,181/989 is 1/3956
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 172,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(172,989) = 43
common factors(in case of two or more numbers have common factors) = 1
GCF(172,989) x common factors =43 x 1 = 43
LCM(172,989) = ( 172 × 989 ) / 43
LCM(172,989) = 170108 / 43
LCM(172,989) = 3956
