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 160,023,443, 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 | 160,023,443 | |
| -1 | -160,023,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,023,443.
Example:
1 x 160,023,443 = 160,023,443
and
-1 x -160,023,443 = 160,023,443
Notice both answers equal 160,023,443
With that explanation out of the way, let's continue. Next, we take the number 160,023,443 and divide it by 2:
160,023,443 ÷ 2 = 80,011,721.5
If the quotient is a whole number, then 2 and 80,011,721.5 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 | 160,023,443 | |
| -1 | -160,023,443 |
Now, we try dividing 160,023,443 by 3:
160,023,443 ÷ 3 = 53,341,147.6667
If the quotient is a whole number, then 3 and 53,341,147.6667 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 | 160,023,443 | |
| -1 | -160,023,443 |
Let's try dividing by 4:
160,023,443 ÷ 4 = 40,005,860.75
If the quotient is a whole number, then 4 and 40,005,860.75 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 | 160,023,443 | |
| -1 | 160,023,443 |
If you did it right, you will end up with this table:
| 1 | 23 | 131 | 173 | 307 | 3,013 | 3,979 | 7,061 | 22,663 | 40,217 | 53,111 | 521,249 | 924,991 | 1,221,553 | 6,957,541 | 160,023,443 |
| -1 | -23 | -131 | -173 | -307 | -3,013 | -3,979 | -7,061 | -22,663 | -40,217 | -53,111 | -521,249 | -924,991 | -1,221,553 | -6,957,541 | -160,023,443 |
