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%2A2 , 40=5%2A8 , and 56=7%2A8 could be values for xy .

24=3%2A8 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.
