Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 163,353,125, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 163,353,125 | |
| -1 | -163,353,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,353,125.
Example:
1 x 163,353,125 = 163,353,125
and
-1 x -163,353,125 = 163,353,125
Notice both answers equal 163,353,125
With that explanation out of the way, let's continue. Next, we take the number 163,353,125 and divide it by 2:
163,353,125 ÷ 2 = 81,676,562.5
If the quotient is a whole number, then 2 and 81,676,562.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 163,353,125 | |
| -1 | -163,353,125 |
Now, we try dividing 163,353,125 by 3:
163,353,125 ÷ 3 = 54,451,041.6667
If the quotient is a whole number, then 3 and 54,451,041.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 163,353,125 | |
| -1 | -163,353,125 |
Let's try dividing by 4:
163,353,125 ÷ 4 = 40,838,281.25
If the quotient is a whole number, then 4 and 40,838,281.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 163,353,125 | |
| -1 | 163,353,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 625 | 1,625 | 3,125 | 4,021 | 8,125 | 20,105 | 40,625 | 52,273 | 100,525 | 261,365 | 502,625 | 1,306,825 | 2,513,125 | 6,534,125 | 12,565,625 | 32,670,625 | 163,353,125 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -625 | -1,625 | -3,125 | -4,021 | -8,125 | -20,105 | -40,625 | -52,273 | -100,525 | -261,365 | -502,625 | -1,306,825 | -2,513,125 | -6,534,125 | -12,565,625 | -32,670,625 | -163,353,125 |
