Know Least Common Multiple of fractions 33/54, 40/15, 38/309 quickly i.e. 8360 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 33/54, 40/15, 38/309 is 8360.
LCM(33/54, 40/15, 38/309) = 8360
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 33/54,40/15,38/309
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 33,40,38
Least Common Multiple of Numerators i.e. LCM of 33,40,38 is 25080.
GCF of Denominators means GCF of 54,15,309 as per the given fractions.
GCF of 54,15,309 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 33,40,38
2 | 33, 40, 38 |
33, 20, 19 |
∴ So the LCM of the given numbers is 2 x 33 x 20 x 19 = 25080
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 33,40,38 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(33,40,38) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(33,40,38) x common factors =1 x 2 = 2
LCM(33,40,38) = ( 33 × 40 × 38 ) / 2
LCM(33,40,38) = 50160 / 2
LCM(33,40,38) = 25080
Lets's calculate GCF of 54,15,309
3 | 54, 15, 309 |
18, 5, 103 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 25080/3
Therefore the LCM of Fractions 33/54,40/15,38/309 is 8360
