Know Least Common Multiple of fractions 18/434, 57/474 quickly i.e. 171 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 18/434, 57/474 is 171.
LCM(18/434, 57/474) = 171
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 18/434,57/474
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 18,57
Least Common Multiple of Numerators i.e. LCM of 18,57 is 342.
GCF of Denominators means GCF of 434,474 as per the given fractions.
GCF of 434,474 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 18,57
3 | 18, 57 |
6, 19 |
∴ So the LCM of the given numbers is 3 x 6 x 19 = 342
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 18,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,57) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(18,57) x common factors =3 x 1 = 3
LCM(18,57) = ( 18 × 57 ) / 3
LCM(18,57) = 1026 / 3
LCM(18,57) = 342
Lets's calculate GCF of 434,474
2 | 434, 474 |
217, 237 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 342/2
Therefore the LCM of Fractions 18/434,57/474 is 171
