How to find the LCM of 100 and 86

The least common multiple of 100 and 86 can be computed by using the greatest common factor aka gcf of 100 and 86. This is the easiest approach:

lcm (100,86) = $\frac{100 \times 86}{gcf(100,86)} = \frac{8600}{2}$ = 4300

Alternatively, the lcm of 100 and 86 can be found using the prime factorization of 100 and 86:

  • The prime factorization of 100 is: 2 x 2 x 5 x 5
  • The prime factorization of 86 is: 2 x 43
  • Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(100,100) = 4300

In any case, the easiest way to compute the lcm of two numbers like 100 and 86 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 100,86. Push the button only to start over.

Use of LCM of 100 and 86

What is the least common multiple of 100 and 86 used for? Answer: It is helpful for adding and subtracting fractions like 1/100 and 1/86. Just multiply the dividends and divisors by 43 and 50, respectively, such that the divisors have the value of 4300, the lcm of 100 and 86.

$\frac{1}{100} + \frac{1}{86} = \frac{43}{4300} + \frac{50}{4300} = \frac{93}{4300}$. $\hspace{30px}\frac{1}{100} – \frac{1}{86} = \frac{43}{4300} – \frac{50}{4300} = \frac{-7}{4300}$.

Properties of LCM of 100 and 86

The most important properties of the lcm(100,86) are:

  • Commutative property: lcm(100,86) = lcm(86,100)
  • Associative property: lcm(100,86,n) = lcm(lcm(86,100),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 100 and 86 is 4300. In common notation: lcm (100,86) = 4300.
