12, 16 and 23 is one possible triplet.
The digits in 51 add up to 6, so it is divisible by 3.51/3 = 17 (17, like 3 is a prime number)so the prime factors of 51 are the two numbers, 3 and 17(51, like all numbers, can also be divided without remainder by 1, but this is not usually counted as a prime factor)
To get the (mean) average, add them up and divide by 3 [since there are 3 numbers]: 12 + 16 + 23 = 51, and 51 ÷ 3 = 17.

Oh, dude, you just add them up and divide by how many numbers there are. So, like, 51 + 52 + 56 = 159, and since there are three numbers, you divide 159 by 3 and get 53. So, the average is 53.

No three odd numbers can add up to an even number.
