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 160,962,875, 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 | 160,962,875 | |
| -1 | -160,962,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,962,875.
Example:
1 x 160,962,875 = 160,962,875
and
-1 x -160,962,875 = 160,962,875
Notice both answers equal 160,962,875
With that explanation out of the way, let's continue. Next, we take the number 160,962,875 and divide it by 2:
160,962,875 ÷ 2 = 80,481,437.5
If the quotient is a whole number, then 2 and 80,481,437.5 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 | 160,962,875 | |
| -1 | -160,962,875 |
Now, we try dividing 160,962,875 by 3:
160,962,875 ÷ 3 = 53,654,291.6667
If the quotient is a whole number, then 3 and 53,654,291.6667 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 | 160,962,875 | |
| -1 | -160,962,875 |
Let's try dividing by 4:
160,962,875 ÷ 4 = 40,240,718.75
If the quotient is a whole number, then 4 and 40,240,718.75 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 | 160,962,875 | |
| -1 | 160,962,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 269 | 1,345 | 4,787 | 6,725 | 23,935 | 33,625 | 119,675 | 598,375 | 1,287,703 | 6,438,515 | 32,192,575 | 160,962,875 |
| -1 | -5 | -25 | -125 | -269 | -1,345 | -4,787 | -6,725 | -23,935 | -33,625 | -119,675 | -598,375 | -1,287,703 | -6,438,515 | -32,192,575 | -160,962,875 |
