Since the smallest prime number is 2, the smallest product of a prime number and 7 is 2 x 7 = 14, and the smallest integer that yields a prime number when it is divided by 14 is 28 (notice that 28/14 = 2).BTGmoderatorDC wrote: ↑Tue Mar 07, 2023 5:41 amWhat is the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number?
