Express the lowest common multiple of 4 5 6 and 9 in its prime factor

To find the lowest common multiple (LCM) of 4, 5, 6, and 9, we need to find the smallest number that is divisible by all of these numbers.

Let's factorize each number into its prime factorization form:
- 4 = 2 * 2
- 5 = 5
- 6 = 2 * 3
- 9 = 3 * 3

Now, let's write all the prime factors together:

2 * 2 * 3 * 3 * 5

By multiplying these prime factors together, we can find the LCM:

2 * 2 * 3 * 3 * 5 = 180

Therefore, the LCM of 4, 5, 6, and 9 in its prime factorization form is 2 * 2 * 3 * 3 * 5.
