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.

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
How many possible 5 digit combInations are there with in ten digits?
In case of digits or numbers, when we say combination, since the order of the numbers matters, we really need to find the permutations. For example, 12 and 21 are two permutations and not combination. The permutation for 10 digits chosen 5 ways is 10*9*8*7*6, which is 30240. But how many are there in whole like four digit has 24.
