im thinkinking to solve this by 9x8x7x6 so on
or 9x9x9x so on i go with the first one more but im not familiar at all with these problems

10x9x8x7x6x5 because there are 10 digits in the numerical system and 6 digits in the pin

i do this, first i put lines for the amount of spaces needed. in this case it is 6 so |dw:1337381854450:dw|
and from 0-9 that is 10 number options so|dw:1337381882083:dw|
so you just multiply 10x9x8x7x6x5
