Know Least Common Multiple of fractions 5451/915, 6819/390 quickly i.e. 12390123/15 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 5451/915, 6819/390 is 12390123/15.
LCM(5451/915, 6819/390) = 12390123/15
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 5451/915,6819/390
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 5451,6819
Least Common Multiple of Numerators i.e. LCM of 5451,6819 is 12390123.
GCF of Denominators means GCF of 915,390 as per the given fractions.
GCF of 915,390 is 15 as it is the largest common factor for these numbers.
Lets's calculate LCM of 5451,6819
3 | 5451, 6819 |
1817, 2273 |
∴ So the LCM of the given numbers is 3 x 1817 x 2273 = 12390123
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 5451,6819 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(5451,6819) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(5451,6819) x common factors =3 x 1 = 3
LCM(5451,6819) = ( 5451 × 6819 ) / 3
LCM(5451,6819) = 37170369 / 3
LCM(5451,6819) = 12390123
Lets's calculate GCF of 915,390
3 | 915, 390 |
5 | 305, 130 |
61, 26 |
∴ So the GCF of the given numbers is 3 x 5 = 15
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12390123/15
Therefore the LCM of Fractions 5451/915,6819/390 is 12390123/15
