the question says: write down all factors of 6

Show that the sum of all the factors of 6 is equal to 2 x 6


(i got the first part right with the factors but i don't know how to do the second part)

asked by Viola
  1. First part:
    The factors of 6, including 6 itself, are:
    1,2,3,6.

    Second part:
    1+2+3+6=12 (=2*6)

    By the way, 6 is a perfect number, namely the sum of the factors (excluding 6 itself) is equal to the number itself.
    The next perfect number is 28 (1+2+4+7+14 = 28)
