Question 826055
According to the definitions I am familiar with,
the factor of 35 are 1, 5, 7, and 35,
while the factors of 16 are 1, 2, 4, 8, and 16.
 
{{{10=5*2}}} , {{{40=5*8}}} , and {{{56=7*8}}} could be values for {{{xy}}} .
 
{{{24=3*8}}} could not be a value for {{{xy}}} because {{{3}}} is not a factor of either {{{35}}} or {{{16}}}, so {{{xy}}} cannot have 3 for a factor.
