Identify Factors of the Prime Number 7

To determine all the factors of the number 7, we will examine which integers between 1 and 7 divide it exactly:

• Check 1: Since $\frac{7}{1} = 7$, 1 is a factor.
• Check 2: $\frac{7}{2} = 3.5$, which is not an integer, so 2 is not a factor.
• Check 3: $\frac{7}{3} \approx 2.333$, which is not an integer, so 3 is not a factor.
• Check 4: $\frac{7}{4} = 1.75$, which is not an integer, so 4 is not a factor.
• Check 5: $\frac{7}{5} = 1.4$, which is not an integer, so 5 is not a factor.
• Check 6: $\frac{7}{6} \approx 1.167$, which is not an integer, so 6 is not a factor.
• Check 7: Since $\frac{7}{7} = 1$, 7 is a factor.

Therefore, the factors of 7 are $1$ and $7$.

These results correspond to choice 1: $1, 7$.
