0 or 5
0 and 5. Every multiple of 5 ends in one of those 2 digits. 5 times any even number ends in 0; 5 times an odd number ends in 5.
You can reduce the number by known factors to make it more manageable. Plus there are tricks for different numbers: If the number is even, then 2 is a factor. If the digits add up to a multiple of 3 then 3 is a factor. If the ones digit is a 5 or 0 (with a tens digit greater than or equal to 1), then 5 is a factor. If the ones digit is a 0 then 10 is a factor. If the digits have the property that the first minus the second, plus the third, minus the fourth, (alternating signs) equals 0, then 11 is a factor. There are other tricks but these factors would be the most common.

They are the same because they are both multiplication. They also can be the same if the two digit number times by the one digit number equals a three digit number. They are different because the 3 digits number will obviously produce a higher product.
The places are always the same no matter what the digits are. The value is obtained by multiplying the place times the digit. Starting from the right, the places in an 8-digit number are ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions and ten millions.
For a number to have 5 as a factor, its ones place must be either 0 or 5. This is because any number that ends in 0 or 5 is divisible by 5. Therefore, the digits that can be in the ones place of a number with 5 as a factor are 0 and 5.
If the original number was even, the ones place will be zero; otherwise it will be 5.
Odd numbers have the digits 1, 3, 5, 7, or 9 in the ones place. These digits indicate that the number cannot be evenly divided by 2. Consequently, any integer ending in one of these digits is classified as an odd number.
If the digits go from the thousands place to the ones place then we need to use 4 digits. Because the digits are all even, we are forced to use the 4 even digits (2, 4, 6 and 8). As they decrease by 2 each time, the only option for ordering them is greatest to lowest. Therefore, the number described in the question is 8,642.
The digits in the ones place of our numbers can be any digit from 0 to 9. This means that for any integer, the ones place will represent the last digit, determining its value in terms of units. For example, in the number 57, the ones place is 7, while in 1234, it is 4. Each number will have a unique digit in the ones place based on its value.
0 and 5. Every multiple of 5 ends in one of those 2 digits. 5 times any even number ends in 0; 5 times an odd number ends in 5.
If 5 is a factor of a number, it means the number is divisible by 5. For the ones digit of the number to be 5, the number must end in 5. Since there are 10 possible digits (0-9), and only one of those digits is 5, the probability of the ones digit being 5 is 1 out of 10, or 1/10.

2,4,6,8,and 0 are divisible by 2 in the ones digit. Zero is only divisible in a number with 2 digits or more. 0 itself is not divisible by 2.
Counting digits: 0 Number of "things" in the ones place: 6 Total "things": 236
