By simply ordering the digits the largest is .5420
15 of them.
Six (6)
There are 600 such numbers.
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
It is 720.

9*8*7 = 504 of them.
3*2*1 = 6 of them.
Without a decimal point, six can. With a decimal point, eighteen can.
