To find the least common multiple (LCM) of 7 and 9, you can use the prime factorization method.

Step 1: Find the prime factorization of each number:

- Prime factorization of 7: 7 is a prime number, so its prime factorization is 7.
- Prime factorization of 9: 9 = 3 * 3 (since 3 is a prime number and 3 * 3 = 9).

Step 2: Identify the highest power of each prime factor:

- The prime factorization of 7 contains one factor of 7.
- The prime factorization of 9 contains two factors of 3.

Step 3: Multiply the highest powers of all prime factors: [ LCM(7, 9) = 7 * 3^2 = 7 * 9 = 63 ]

Therefore, the least common multiple of 7 and 9 is 63.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
