Hi,
I read definition of GCD theorem, from book and from mathWorld website.
"
There are two different statements, each separately known as the greatest common divisor theorem.
This does not make sanse
1. Given positive integers
and
, it is possible to choose integers
and
such that
, where
is the greatest common divisor of
and
(Eynden 2001).
This make sense
2. If
and
are relatively prime positive integers, then there exist positive integers
and
such that
(Johnson 1965).
"
======================================
if I take 2nd definition from above
and take
m=12
n=7
then divisors:
12X1,6x2,4x3
7x1
gdc=1
and according to second definition.
x=3
y=5
xm - ny = 1
(12x3 ) - (7x5) = 1
36 -35 = 1
it make sense.
========================================
but 1st definition says
,
we take again
m=12 and
n=7
no matter what values of 'x' and 'y' we pick, we can not make d smaller so it can become '1'.
Unless we select negative x and y.
