HP Prime - Finding the LCM

LCM or Least Common Multiple

Entering lcm(Number1, Number2) will return the least common multiple of the two numeric values. The lcm function will only accepts two values at a time.

Find the LCM for 10, 15, and 45.

  1. Press [CAS] key
  2. Enter lcm(10,15) and press [Enter] key.
  3. It should display the result of 30.
  4. Enter lcm(30,45) and press [Enter] key.
  5. It should display the final result of 90.

Since LCM can only accept two entries at a time, find the LCM of the first two values, and then find the LCM of your answer and the third value.
