Solution:
Prime factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number.
Given:
Using a tree diagram;
[tex]\begin{gathered} 663=3\times221=3\times(13\times17) \\ 663=3\times13\times17 \end{gathered}[/tex]Hence, 663 = 3 x 13 x 17
Using a tree diagram;
[tex]\begin{gathered} 442=2\times221=2\times(13\times17) \\ 442=2\times13\times17 \end{gathered}[/tex]Hence, 442 = 2 x 13 x 17
