Know Least Common Multiple of fractions 115/20, 390/6836 quickly i.e. 8970/4 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 115/20, 390/6836 is 8970/4.
LCM(115/20, 390/6836) = 8970/4
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 115/20,390/6836
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 115,390
Least Common Multiple of Numerators i.e. LCM of 115,390 is 8970.
GCF of Denominators means GCF of 20,6836 as per the given fractions.
GCF of 20,6836 is 4 as it is the largest common factor for these numbers.
Lets's calculate LCM of 115,390
5 | 115, 390 |
23, 78 |
∴ So the LCM of the given numbers is 5 x 23 x 78 = 8970
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 115,390 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(115,390) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(115,390) x common factors =5 x 1 = 5
LCM(115,390) = ( 115 × 390 ) / 5
LCM(115,390) = 44850 / 5
LCM(115,390) = 8970
Lets's calculate GCF of 20,6836
2 | 20, 6836 |
2 | 10, 3418 |
5, 1709 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8970/4
Therefore the LCM of Fractions 115/20,390/6836 is 8970/4
