If 8 and 5 are factors of what product?

• A. 40
• B. 30
• C. 25
• D. 15

Answer: (A)

To determine the product for which 8 and 5 are factors, it's important to recall that a factor is a number that can evenly divide another number without leaving a remainder. In this case, we need to identify a product formed by multiplying 8 and 5 together.

Calculating the product of 8 and 5 gives us 40 (since 8 × 5 = 40). This means that 40 is the number that has both 8 and 5 as factors because it can be divided evenly by both of these numbers.

When looking at the provided choices, 40 stands out as it confirms that both 8 and 5 can multiply to yield exactly this number. The other options (30, 25, and 15) do not satisfy the requirement that both 8 and 5 divide into them as whole numbers without leaving a remainder. Therefore, the correct answer, which is the product of 8 and 5, is 40.
