Determine the Number with Prime Factors 5 and 11

What is the number whose prime factors are: $5,11$

To find the number whose prime factors are $5$ and $11$, we need to multiply these factors together. Let's do this step by step:

• Multiply the prime factors: $5 \times 11$.

Performing the multiplication, we calculate:

$5 \times 11 = 55$.

Therefore, the number whose prime factors are $5$ and $11$ is $55$.

From the choices provided, the correct answer is $55$, which corresponds to choice 3.
