what numbers i can use to make a prime factorization of 72

Answer 1

To perform prime factorization of the number 72, you can use the following steps:

1. Start dividing by the smallest prime number, which is 2:

   • $72÷2=36$
   • $36÷2=18$
   • $18÷2=9$

2. Now, 9 cannot be divided by 2 anymore, so we move to the next smallest prime, which is 3:

   • $9÷3=3$
   • $3÷3=1$

Now that we have reached 1, we can collect all the prime factors we've used:

• The prime factorization of 72 is: $$72=2^3\times 3^2$$

Thus, the prime factors of 72 are 2 and 3.
