Using divisibility tests, determine which of the following  numbers are divisible by 4; by 8:(a)  572          (b) 726352     (c)  5500            (d)  6000           (e)  12159(f)  14560      (g)  21084      (h)  31795072     (i)  1700            (j)  2150

Solution: a)72/4=18, So, 572 is divisible by 4
b)52/4=13, So, 726352 is divisible by 4
c)00/4=0, So, 5500 is divisible by 4
d)00/4=0, So, 6000 is divisible by 4
e)59/4=14.8, So, 12159 is not divisible by 4
f)60/4=15, So, 14560 is divisible by 4
g)84/4=21, So, 21084 is divisible by 4
h)72/4=18, So, 31795072 is divisible by 4
i)00/4=0, So, 1700 is divisible by 4
j)50/4=12.5, So, 2150 is not divisible by 4.
