what numbers i can use to make in exponents a prime factorization of 198

1 answer

To perform a prime factorization of the number \(198\), we can break it down into its prime factors.

  1. Start by dividing \(198\) by the smallest prime number, which is \(2\): \[ 198 \div 2 = 99 \] Thus, \(198 = 2 \times 99\).

  2. Next, we factor \(99\). The smallest prime that divides \(99\) is \(3\): \[ 99 \div 3 = 33 \] Therefore, \(99 = 3 \times 33\) and we have \(198 = 2 \times 3 \times 33\).

  3. Now, we continue factoring \(33\). The smallest prime dividing \(33\) is \(3\) again: \[ 33 \div 3 = 11 \] So \(33 = 3 \times 11\) and we have \(198 = 2 \times 3 \times 3 \times 11\), or \(198 = 2 \times 3^2 \times 11\).

  4. Now, \(11\) is a prime number and cannot be factored further.

Therefore, the prime factorization of \(198\) is: \[ 198 = 2^1 \times 3^2 \times 11^1 \]

In summary, the prime factors of \(198\) are \(2\), \(3\), and \(11\) in exponential form \(2^1, 3^2, 11^1\).
