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 162,503,459, 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 | 162,503,459 | |
| -1 | -162,503,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,503,459.
Example:
1 x 162,503,459 = 162,503,459
and
-1 x -162,503,459 = 162,503,459
Notice both answers equal 162,503,459
With that explanation out of the way, let's continue. Next, we take the number 162,503,459 and divide it by 2:
162,503,459 ÷ 2 = 81,251,729.5
If the quotient is a whole number, then 2 and 81,251,729.5 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 | 162,503,459 | |
| -1 | -162,503,459 |
Now, we try dividing 162,503,459 by 3:
162,503,459 ÷ 3 = 54,167,819.6667
If the quotient is a whole number, then 3 and 54,167,819.6667 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 | 162,503,459 | |
| -1 | -162,503,459 |
Let's try dividing by 4:
162,503,459 ÷ 4 = 40,625,864.75
If the quotient is a whole number, then 4 and 40,625,864.75 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 | 162,503,459 | |
| -1 | 162,503,459 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 53 | 83 | 697 | 901 | 1,411 | 2,173 | 2,809 | 3,403 | 4,399 | 36,941 | 47,753 | 57,851 | 74,783 | 115,169 | 180,359 | 233,147 | 1,957,873 | 3,066,103 | 3,963,499 | 9,559,027 | 162,503,459 |
| -1 | -17 | -41 | -53 | -83 | -697 | -901 | -1,411 | -2,173 | -2,809 | -3,403 | -4,399 | -36,941 | -47,753 | -57,851 | -74,783 | -115,169 | -180,359 | -233,147 | -1,957,873 | -3,066,103 | -3,963,499 | -9,559,027 | -162,503,459 |
