Hi All,

We're asked to find the smallest integer that can be DIVIDED by the PRODUCT of a PRIME number and 7 AND will yield a PRIME number as the result. We can answer this question by TESTing THE ANSWERS.

Since we're asked for the SMALLEST number that will fit the above information, we should start with Answer A: 7....

The smallest product that can occur between 7 and a prime is (7)(2) = 14. 7 is NOT divisibly by 14, so we can eliminate Answer A.

Answer B: 14...

While 14 is divisible by 14, the end result is 1 - but that is NOT a prime number. Eliminate Answer B.

Answer C: 24

24/14 is NOT a prime. The next two products to consider would be (7)(3) = 21 and (7)(5) = 35. However, 24/21 and 24/35 are NOT primes. Eliminate Answer C.

Answer D: 28

28/14 = 2 - and that IS a prime. This matches everything we were told, so this must be the answer.

Final Answer:
