The other number is #color(green)(""(-20))#

Explanation:

Given that one number is #(-17)#, let the other number be represented by the variable #x#.

We are told that #340# is the product of #(-17)# and #x#.

That is
#color(white)("XXX")(-17) xx x= 340#

If we divide both sides by #(-17)#
#color(white)("XXX") (cancel(""(-17))xx x)/cancel(""(-17)) = (cancel(340)^(-20))/cancel(""(-17)))#

#color(white)("XXX")x =-20#

The other number is #-20#.

Explanation:

Let #-17# equal the known factor and #x# equal the unknown factor.

#-17*x=340#

Simplify.

#-17x=340#

Divide both sides by #-17#.

#x=-20#
