Know Least Common Multiple of fractions 636/84, 238/20, 171/238 quickly i.e. 2156994 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 636/84, 238/20, 171/238 is 2156994.
LCM(636/84, 238/20, 171/238) = 2156994
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 636/84,238/20,171/238
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 636,238,171
Least Common Multiple of Numerators i.e. LCM of 636,238,171 is 4313988.
GCF of Denominators means GCF of 84,20,238 as per the given fractions.
GCF of 84,20,238 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 636,238,171
2 | 636, 238, 171 |
3 | 318, 119, 171 |
106, 119, 57 |
∴ So the LCM of the given numbers is 2 x 3 x 106 x 119 x 57 = 4313988
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 636,238,171 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(636,238,171) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(636,238,171) x common factors =1 x 6 = 6
LCM(636,238,171) = ( 636 × 238 × 171 ) / 6
LCM(636,238,171) = 25883928 / 6
LCM(636,238,171) = 4313988
Lets's calculate GCF of 84,20,238
2 | 84, 20, 238 |
42, 10, 119 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4313988/2
Therefore the LCM of Fractions 636/84,238/20,171/238 is 2156994
