It really depends on what operations are allowed, and whether you are allowed to repeat operations. If you find one way, you can extend that to infinitely many ways. Since the factorial of 1 is 1, you can add as many exclamation marks as you want.
There are 840 4-digit combinations without repeating any digit in the combinations.

your a very unegucated chill i hope you burn in hell
I take it that you want to make three digits numbers with 8,7,3, and 6 without repetition. The first digit cane be selected from among 4 digits, the second from 3 digits, the third digit from 2, hence the number of three digit numbers that can be formed without repetition is 4 x 3 x 2 = 24
