All numbers are a composite value of the sum of all its place values. These place values are the values given to each digit of a number that it holds. The values are multiples of 10. Starting from the very right digit going to the left, the placement of the digits are ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, hundred millions, etc. The concept is that the adjacent place values are 10 times greater than the other.
So, for this number, we just have to add the number of place values with their respective values:
30(1) + 82(1,000) + 4(100,000) + 60(10) + 100(100)
The sum is equal to 492,630. Therefore, the number is 492,630.
