48 of them if digits may not be repeated. 100 if they can.
If the digits can be used more than once, then 900. If not, then 648.
Forming three three digit numbers that use the numbers 1-9 without repeating, the highest product possible is 611,721,516. This is formed from the numbers 941, 852, and 763.
5 x 10 x 5 = 250 different numbers, assuming there is no limit to each digits' use.

27 three digit numbers from the digits 3, 5, 7 including repetitions.
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
48 of them if digits may not be repeated. 100 if they can.
There are 900 three-digit numbers.
If the digits can be used more than once, then 900. If not, then 648.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.

Forming three three digit numbers that use the numbers 1-9 without repeating, the highest product possible is 611,721,516. This is formed from the numbers 941, 852, and 763.
5 x 10 x 5 = 250 different numbers, assuming there is no limit to each digits' use.
24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.
24+24+12+4=64.
