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.

Example:

Find the LCM for 10, 15, and 45.

- Press [ CAS] key
- Enter lcm(10,15) and press [Enter] key.
- It should display the result of 30.
- Enter lcm(30,45) and press [Enter] key.
- 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.
