Proof of size of divisors

  1. Mar 9, 2012 #1
    could any body help me prove this

    if a,b,c are integers and b doesnt equal zero

    if a| b then |a| < | b|

    in particular any divisors a of a positive divisor b must fall in the interval 1 < a <b

    1) It's not a strict inequality

    2) It follows from the definition of divisor
