54, 99 / 2 = 27, 99 27, 99 / 3 = 9, 33 9, 33 / 3 = 3, 11 3, 11 / 3 = 1, 11 1, 11 / 11 = 1, 1 SCM = 2 x 3^3 x 11
The LCM of 9 and 11 is 99 and the method is: (The factor tree method) 1.Start off with 9 and think of ANY pair of numbers that MULTIPLIED together makes 9 which would be 3 and 3. Because 3 is a prime number, you stop dividing. (If in other situations, the numbers aren't prime numbers yet, carry on until they are.) 2. (The same process with the other number normally) But in this case, 11 is already a prime number so you don't do anything with it. 3. (Last step in this case) 3 x 3 x 11 = 99 :)
