the question does not make sense, as it stands.if the 4 refers to the idea of providing 4 specific numbers and then combining them in different waysthere are lots of combinations such as adding them or multiplying them, etc., but.....if you mean combining the numbers by listing all 4 of them in different orders, that's called permutation, not combination. How many ways? Well, there are 4 ways of choosing which one comes first, then three choices for the next and two for the next, so you have 24 ways.If you are interested in combinations of numbers that's different. you my wish to select just one , two, three or all 4 of a set of numbers.If the order didn't matter, there is 1 way of selecting none of them, 4 ways of only choosing one, and six ways of choosing only 2, 4 ways of choosing three,1 way of choosing all 4. that's 16 combinations.If the order matters, you have to permute each of your combinations. 65 possible results!
That's an infinite list.
The factors of 65 are 1, 5, 13, and 65.

23, 97 and 47 are prime numbers. They are only divisible by them and 1 number.
The average of 56, 62, 65, 68, and 74 is 65. The average is calculated by adding up all the numbers and dividing by the total count of numbers.
All of them except 67, 71 and 73 which are prime numbers
Just 17.
38.25 is the average The way you do it is...add all the numbers, then divide that number by the numbers of numbers you just added. 65+49+24+15=153 153/4=38.25
65 + 97 = 162 97 - 65 = 162 The two numbers are therefore 65 and 97.
That's an infinite list.
65 = LXV
