What is the Least Common Multiple of 9 and 2?

The least common multiple (LCM) of 9 and 2 is 18. To find the LCM, you can use the prime factorization method. To do this, you will first find the prime factorization of 9 and 2. 9 = 3 x 3 and 2 = 2. Then, multiply each factor the maximum number of times it occurs in either number. The LCM of 9 and 2 is 3 x 3 x 2 = 18.

Steps to find the LCM of 9 and 2

The steps to find the LCM of 9 and 2 are:

  • Find the prime factorization of 9 – 9 = 3 x 3
  • Find the prime factorization of 2 – 2 = 2
  • Multiply each factor the greatest number of times it occurs in steps 1 or 2 – LCM = 2 x 3 x 3 4. LCM = 18.
