Question

one way to determine whether a number is prime or composite is by crea table.
complete the factor table and the sentences below about the number 17.
factor pairs of 17
1 17
2 not a factor
3 not a factor
4 4
5 not a factor

Explanation:

Step1: Recall factor definition

A factor of a number \( n \) is an integer that divides \( n \) without leaving a remainder. For \( 17 \), we check if \( 4 \) divides \( 17 \).

Step2: Check divisibility by 4

Calculate \( 17\div4 \). \( 4\times4 = 16 \), and \( 17 - 16 = 1 \), so there is a remainder of \( 1 \). Thus, \( 4 \) is not a factor of \( 17 \).

Answer:

For the row with \( 4 \) in the "Factor Pairs of 17" table, the correct entry is "not a factor".
