There are twenty numbers between 19 through 39, including 19 and 39. So the problem is 20 times 20 times 20 times 20 times 20. 320,0000

The question, as stated, cannot be answered because there are only 26 = 64 combinations. The order of the numbers in a combination does make a difference so 134 is the same as 143 or 413 etc. There are 1 combinations each of 0 and 6 of the numbers, 6 combinations of 1 or 5 numbers, 15 combinations of 2 or 4 numbers, and 20 combinations of 3 numbers. The list includes the null combination - that is the combination consisting of none of the numbers.

No combinations of even numbers can be relatively prime.

Assuming you are using "combinations" in the mathematical sense where order doesn't matter (if order does matter it would be "permutations"), there are 22C5 = 22!/5!17! = 26,334 possible combinations of 5 numbers from 22. They start {1, 2, 3, 4, 5}, {1, 2, 3, 4, 6}, {1, 2, 3, 4, 7}, ... and end ... {16, 19, 20, 21, 22}, {17, 19, 20, 21, 22}, {18, 19, 20, 21, 22}; I'll leave the 26,328 combinations in the middle for you to list.

There are 1140 5 digit combinations from 1 to 20. 20 combination 3 computes that.
