There are five cards with 1, 3, 4, 6 and 8. How many numbers can be divided by 2

The number divisible by 2 is even, and the last digit must be even 4, or 6, or 8
Even numbers in the numbers composed of 1, 3, 4, 6 and 8 are as follows:
Single digit: 3
Tens: 3 * 4 = 12
Hundreds: 3 * (4 * 3) = 36
Thousand digits: 3 * (4 * 3 * 2) = 72
10000 digits: 3 * (4 * 3 * 2 * 1) = 72
There are 3 + 12 + 36 + 72 + 72 = 195
