Answer:
6
Explanation:
The factors listed shows that 1 x 32 = 32, 2x 16= 32, 4 x 8= 32
BUT! When we get to 6 it does not have a number to multiply to that is a whole number. For example, 32/6= 5.333 which is not a whole number. Factors have to be whole numbers and no decimals! So, 6 should be removed from the list to make it accurate!
