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 160,586,023, 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 | 160,586,023 | |
| -1 | -160,586,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,586,023.
Example:
1 x 160,586,023 = 160,586,023
and
-1 x -160,586,023 = 160,586,023
Notice both answers equal 160,586,023
With that explanation out of the way, let's continue. Next, we take the number 160,586,023 and divide it by 2:
160,586,023 ÷ 2 = 80,293,011.5
If the quotient is a whole number, then 2 and 80,293,011.5 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 | 160,586,023 | |
| -1 | -160,586,023 |
Now, we try dividing 160,586,023 by 3:
160,586,023 ÷ 3 = 53,528,674.3333
If the quotient is a whole number, then 3 and 53,528,674.3333 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 | 160,586,023 | |
| -1 | -160,586,023 |
Let's try dividing by 4:
160,586,023 ÷ 4 = 40,146,505.75
If the quotient is a whole number, then 4 and 40,146,505.75 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 | 160,586,023 | |
| -1 | 160,586,023 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 59 | 299 | 767 | 1,357 | 9,103 | 17,641 | 118,339 | 209,369 | 537,077 | 2,721,797 | 6,982,001 | 12,352,771 | 160,586,023 |
| -1 | -13 | -23 | -59 | -299 | -767 | -1,357 | -9,103 | -17,641 | -118,339 | -209,369 | -537,077 | -2,721,797 | -6,982,001 | -12,352,771 | -160,586,023 |
