"The" five multiples is wrong; each integer has infinitely many multiples, not just five. To get multiples, in this case, please calculate: 30 x 1 30 x 2 etc.

The first five multiples of 38 is different from the first five multiples of 20! Who idoit would say they are the same?! Anyway these are the multiples... 38, 76, 114, 152, 190, 228. WELCOME :)
