katrin2010 [14]

Answer:

5 integers: {4, 6, 8, 12, 24}

Step-by-step explanation:

From the given info we have:

99 - 3 = 96 is divisible by the number, the number is greater than 3 since the remainder was 3.
70 + 2 = 72 is divisible by same number.

Using the above info, find all factors of the two numbers, greater than 3:

96 = 4*24 = 6*16 = 8*12 = 12*8 = 16*6 = 24*4 = 32*3 = 48*2
72 = 4*18 = 6*12 = 8*9 = 12*6 = 18*4 = 24*3 = 36*2

The common divisors are:

4, 6, 8, 12, 24
