The first digit can be one of {1, 2, 3, 4, 5, 6, 8}, ie one of 7 digits;
for each of these, the second digit can be one of {0, 1, 2, 3, 4, 5, 6, 8}, ie one of 8 digits;
for each of these two, the third digit can also be one of {0, 1, 2, 3, 4, 5, 6, 8}, ie one of 8 digits;
making 7 × 8 × 8 = 488 such three digit numbers.

A whole number consists of the digits 2 4 6 8 and 0 If each digit is used only once how many whole numbers are possible?
There are 5 digits in 24680; think of them as 5 compartments. You can select 5 numbers for the 1st compartment, 4 numbers for the 2nd compartment, 3 numbers for the 3rd compartment, 2 numbers for the 4th compartment, and 1 number for the 5th compartment. So, the answer is 5*4*3*2*1 or 5! or 120
