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 163,006,463, 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 | 163,006,463 | |
| -1 | -163,006,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,006,463.
Example:
1 x 163,006,463 = 163,006,463
and
-1 x -163,006,463 = 163,006,463
Notice both answers equal 163,006,463
With that explanation out of the way, let's continue. Next, we take the number 163,006,463 and divide it by 2:
163,006,463 ÷ 2 = 81,503,231.5
If the quotient is a whole number, then 2 and 81,503,231.5 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 | 163,006,463 | |
| -1 | -163,006,463 |
Now, we try dividing 163,006,463 by 3:
163,006,463 ÷ 3 = 54,335,487.6667
If the quotient is a whole number, then 3 and 54,335,487.6667 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 | 163,006,463 | |
| -1 | -163,006,463 |
Let's try dividing by 4:
163,006,463 ÷ 4 = 40,751,615.75
If the quotient is a whole number, then 4 and 40,751,615.75 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 | 163,006,463 | |
| -1 | 163,006,463 |
If you did it right, you will end up with this table:
| 1 | 31 | 97 | 151 | 359 | 3,007 | 4,681 | 11,129 | 14,647 | 34,823 | 54,209 | 454,057 | 1,079,513 | 1,680,479 | 5,258,273 | 163,006,463 |
| -1 | -31 | -97 | -151 | -359 | -3,007 | -4,681 | -11,129 | -14,647 | -34,823 | -54,209 | -454,057 | -1,079,513 | -1,680,479 | -5,258,273 | -163,006,463 |
