What is the LCM of 50 and 15

If you just want to know what is the least common multiple of 50 and 15, it is 150. Usually, this is written as

lcm(50,15) = 150

The lcm of 50 and 15 can be obtained like this:

  • The multiples of 50 are …, 100, 150, 200, ….
  • The multiples of 15 are …, 135, 150, 165, …
  • The common multiples of 50 and 15 are n x 150, intersecting the two sets above, $\hspace{3px}n \hspace{3px}\epsilon\hspace{3px}\mathbb{Z}$.
  • In the intersection multiples of 50 ∩ multiples of 15 the least positive element is 150.
  • Therefore, the least common multiple of 50 and 15 is 150.

Taking the above into account you also know how to find all the common multiples of 50 and 15, not just the smallest. In the next section we show you how to calculate the lcm of fifty and fifteen by means of two more methods.

How to find the LCM of 50 and 15

The least common multiple of 50 and 15 can be computed by using the greatest common factor aka gcf of 50 and 15. This is the easiest approach:

lcm (50,15) = $\frac{50 \times 15}{gcf(50,15)} = \frac{750}{5}$ = 150

Alternatively, the lcm of 50 and 15 can be found using the prime factorization of 50 and 15:

  • The prime factorization of 50 is: 2 x 5 x 5
  • The prime factorization of 15 is: 3 x 5
  • Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(50,50) = 150

In any case, the easiest way to compute the lcm of two numbers like 50 and 15 is by using our calculator below. Note that it can also compute the lcm of more than two numbers, separated by a comma. For example, enter 50,15. Push the button only to start over.

Use of LCM of 50 and 15

What is the least common multiple of 50 and 15 used for? Answer: It is helpful for adding and subtracting fractions like 1/50 and 1/15. Just multiply the dividends and divisors by 3 and 10, respectively, such that the divisors have the value of 150, the lcm of 50 and 15.

$\frac{1}{50} + \frac{1}{15} = \frac{3}{150} + \frac{10}{150} = \frac{13}{150}$. $\hspace{30px}\frac{1}{50} – \frac{1}{15} = \frac{3}{150} – \frac{10}{150} = \frac{-7}{150}$.

Properties of LCM of 50 and 15

The most important properties of the lcm(50,15) are:

  • Commutative property: lcm(50,15) = lcm(15,50)
  • Associative property: lcm(50,15,n) = lcm(lcm(15,50),n) $\hspace{10px}n\neq 0 \hspace{3px}\epsilon\hspace{3px}\mathbb{Z}$

The associativity is particularly useful to get the lcm of three or more numbers; our calculator makes use of it.

To sum up, the lcm of 50 and 15 is 150. In common notation: lcm (50,15) = 150.
