To express the prime factorization of 144, we can break it down as follows:
144 can be divided by 2:
- 144 ÷ 2 = 72
- 72 ÷ 2 = 36
- 36 ÷ 2 = 18
- 18 ÷ 2 = 9
- 9 ÷ 3 = 3
- 3 ÷ 3 = 1
Counting the number of times we divided by each prime factor, we get:
- 2 appears 4 times, and
- 3 appears 2 times.
Thus, the prime factorization of 144 is:
\( 2^4 \cdot 3^2 = 144 \)
So, the answer is:
\( 2^4 \cdot 3^2 = 144 \)
