2, 3 and 73
83, 3,and 2 are prime numbers which add up to 88.
No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime

The numbers are: 12 and -15
when you add the numbers it will add up to a multiple of 3. Lets say 12 1+2=3 or 36 3+6=9, they are all multiples of 3.
Add all the numbers up and divide by how many there are... Example: 10,11,12 add them up: 10+11+12= 33 then divide by how many numbers there are... 3 33/3 = 11
The factor pairs of 12 are (12, 1) (6, 2) (4, 3) None of them add up to 5.

There are several pairs of numbers that add up to 12, including 6 and 6, 5 and 7, or 3 and 9. Any combination of two numbers that sums to 12 is valid, as long as their total equals that amount.
any 3 numbers that add up to 48, e.g. 12+23+13 or 24+23+1 the list goes on but the 3 numbers MUST add up to 48 to get the mean of 16
