Answer:

Step-by-step explanation:
The number can be divisible by 7.
The multiples of 7 are 7,14,21,28,35,42,49,56,63,70,77,84 and so on
<u>Finding the factors for all of the multiples of 7:</u>
7 => 1,7   [Not 4 factors]
14 => 1,2,7,14    [4 factors but Sum = 24]
21 => 1,3,7,21   [4 factors but Sum = 32]
28 => 1, 2, 4, 7, 14, 28    [Not 4]
35 => 1,5,7,35   [4 factors but Sum = 48]
42 => 1, 2, 3, 6, 7, 14, 21, 42     [Not 4]
49 => 1,7,49   [Not 4]
56 => 1, 2, 4, 7, 8, 14, 28, 56       [Not 4]
63 => 1, 3, 7, 9, 21, 63     [Not 4]
70 => 1, 2, 5, 7, 10, 14, 35, 70    [Not 4]
77 => 1, 7, 11, 77     [4 factors and Sum = 96]
