171
The numbers are: (-12+square root of 171) and (-12-square root of 171)
None!!! Because '171' is NOT an EVEN number. Remember even numbers end in 0,2,4,6,and 8. Since '171', does not end in 0,2,4,6 or 8 , then it is not an even number, so it will not divide evenly. NB However, you can divide '171' by '2' , and the answer is 85.5 or 85 1/2
The numbers 1, 3 and 9 all go into both 72 and 171.
If you include 8 and 171, there would be 171-8+1 = 164 If you dont include both, it would be2 less -> 162

You need at least two numbers to find a GCF.
171
To find two numbers that multiply to 171, we can start by breaking down 171 into its prime factors: 3 x 3 x 19. Since 171 is not a perfect square, the two numbers that multiply to 171 are 3 and 57. So, 3 x 57 = 171.
171 = 171/1 and 109 = 109/1 are fractional representations of the numbers.
The numbers are: (-12+square root of 171) and (-12-square root of 171)
The multiples of 171 (which are infinite) are all divisible by 171 , including these: 171, 342, 513, 684, 855, 1026, 1197, 1368, 1539 . . .
171 - 38 = 133 so 133 + 38 sum to 171

Add them altogether. 143+193+169+155+171+155 = 986 Now divide the sum by the amount of numbers you added, which is 6. You added 6 numbers to equal 986. 986/6=164.333. round that and you get 164. The mean of this group is 164
