To find the least common multiple (LCM) of the numbers 2, 5, and 3, we need to identify the smallest number that is a multiple of all three.

Step-by-Step Calculation

First, let's list the multiples of each number:

  • Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, ...
  • Multiples of 5: 5, 10, 15, 20, 25, ...
  • Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, ...

Finding the Common Multiple

Next, we look for the smallest number that appears in all three lists:

  • 10 is a multiple of 2 and 5.
  • 15 is a multiple of 5 and 3.
  • 6 is a multiple of 2 and 3.
  • However, 30 is the first number that is a multiple of 2, 5, and 3.

The Result

Thus, the least common multiple of 2, 5, and 3 is 30.
