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 160,107,101, 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 | 160,107,101 | |
| -1 | -160,107,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,107,101.
Example:
1 x 160,107,101 = 160,107,101
and
-1 x -160,107,101 = 160,107,101
Notice both answers equal 160,107,101
With that explanation out of the way, let's continue. Next, we take the number 160,107,101 and divide it by 2:
160,107,101 ÷ 2 = 80,053,550.5
If the quotient is a whole number, then 2 and 80,053,550.5 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 | 160,107,101 | |
| -1 | -160,107,101 |
Now, we try dividing 160,107,101 by 3:
160,107,101 ÷ 3 = 53,369,033.6667
If the quotient is a whole number, then 3 and 53,369,033.6667 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 | 160,107,101 | |
| -1 | -160,107,101 |
Let's try dividing by 4:
160,107,101 ÷ 4 = 40,026,775.25
If the quotient is a whole number, then 4 and 40,026,775.25 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 | 160,107,101 | |
| -1 | 160,107,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 791 | 1,243 | 8,701 | 18,401 | 128,807 | 202,411 | 1,416,877 | 2,079,313 | 14,555,191 | 22,872,443 | 160,107,101 |
| -1 | -7 | -11 | -77 | -113 | -791 | -1,243 | -8,701 | -18,401 | -128,807 | -202,411 | -1,416,877 | -2,079,313 | -14,555,191 | -22,872,443 | -160,107,101 |
