60. There are 5 different choices for the first digit, four for the second digit, and three choices for the third digit. According to the fundamental counting principle, you multiply them together to get the total number of possible ways, and 5 x 4 x 3 = 60 Another way to think about it is 5!/3!

The 3-digit counting numbers are 100 through 999 = 900 numbers.Half them are multiples of 2 (even numbers).The other half are not . . . 450 of them.
There are 898 three-digit even numbers. Nine of them are multiples of 55. That leaves 889 * * * * * There are 450 three-digit even numbers and 17 of them are multiples of 55. So that leaves 433.
There are 9*10*9 = 810 such numbers.
Three-digit counting numbers range from 100 to 999. To find how many of these are multiples of 2, we note that the smallest three-digit multiple of 2 is 100, and the largest is 998. The sequence of three-digit multiples of 2 can be represented as 100, 102, 104, ..., 998, which forms an arithmetic sequence with a common difference of 2. The total number of terms in this sequence can be calculated as ((998 - 100) / 2 + 1), resulting in 450 three-digit counting numbers that are multiples of 2.
There are 720 of them. The three digit counting numbers are 100-999. All multiples of 5 have their last digit as 0 or 5. There are 9 possible numbers {1-9} for the first digit, There are 10 possible numbers {0-9} for each of the first digits, There are 8 possible numbers {1-4, 6-9} for each of the first two digits, Making 9 x 10 x 8 = 720 possible 3 digit counting numbers not multiples of 5.

Any three-digit multiple of 60, from 120 to 960, has the first five counting numbers as factors.
To find the three-digit numbers that are multiples of 16, we first identify the smallest and largest three-digit multiples of 16. The smallest three-digit number is 100, and the smallest multiple of 16 greater than or equal to 100 is 112 (16 x 7). The largest three-digit number is 999, and the largest multiple of 16 less than or equal to 999 is 992 (16 x 62). To find the total number of three-digit multiples of 16, we calculate the range from 7 to 62, which gives us 62 - 7 + 1 = 56 three-digit multiples of 16.
