174 =============== 18 = 15+3 54 = 18x3 57 = 54+3 171= 57x3 174= 171+3

171 - 38 = 133 so 133 + 38 sum to 171

131 all have odd numbers, so does 151 and 171. i would say 161 is the one that doesn't belong because it has an even number in it.

15

the next two are 174 and 522.

You need at least two numbers to find a GCF.

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

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

171

The numbers 1, 3 and 9 all go into both 72 and 171.

No. They are both composite numbers. They are not relatively prime either.

If you include 8 and 171, there would be 171-8+1 = 164 If you dont include both, it would be2 less -> 162
