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 160,323,653, 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 | 160,323,653 | |
| -1 | -160,323,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,323,653.
Example:
1 x 160,323,653 = 160,323,653
and
-1 x -160,323,653 = 160,323,653
Notice both answers equal 160,323,653
With that explanation out of the way, let's continue. Next, we take the number 160,323,653 and divide it by 2:
160,323,653 ÷ 2 = 80,161,826.5
If the quotient is a whole number, then 2 and 80,161,826.5 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 | 160,323,653 | |
| -1 | -160,323,653 |
Now, we try dividing 160,323,653 by 3:
160,323,653 ÷ 3 = 53,441,217.6667
If the quotient is a whole number, then 3 and 53,441,217.6667 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 | 160,323,653 | |
| -1 | -160,323,653 |
Let's try dividing by 4:
160,323,653 ÷ 4 = 40,080,913.25
If the quotient is a whole number, then 4 and 40,080,913.25 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 | 160,323,653 | |
| -1 | 160,323,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 41 | 133 | 287 | 779 | 5,453 | 29,401 | 205,807 | 558,619 | 1,205,441 | 3,910,333 | 8,438,087 | 22,903,379 | 160,323,653 |
| -1 | -7 | -19 | -41 | -133 | -287 | -779 | -5,453 | -29,401 | -205,807 | -558,619 | -1,205,441 | -3,910,333 | -8,438,087 | -22,903,379 | -160,323,653 |
