If x and 105/x are both natural numbers, list down all the possible values of x.
I understand natural numbers are from positive integers from 1 onwards. so x cannot exceed 105.
my answer is ( 1,2,3... all the way of increasing order of +1 to 105)
but my answer is wrong. can the maths genius explain, thanks!
hi the factors of 105 are 1,3,5,7,15,21,35, and 105
but the answer is only 1,3,5,7, 35 and 105, meaning 15 & 21 not considered( i thought should be in the answer cuz when 105/15= 7 and 105/21= 5, both are integers)..how come not right?

I do not wish to argue with your answer sheet, but 15 and 21 should be considered answers too, unless they have some other mathematical conditions listed down.
15 and 21 should be in too.
