Well, honey, in the number 456802, the digit with the least value is 0. It's like the extra in a movie - it's there to fill space but doesn't really bring much to the table. So, yeah, that 0 is just hanging out, being all insignificant and whatnot.
The "7" digit had the greatest value because it is in the UNITS column.
The digit with the second greatest value in the number is '1'. its value is second to the largest number which is 2.
0 has the least face value, 2 has the least place value.
