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 160,156,643, 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 | 160,156,643 | |
| -1 | -160,156,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,156,643.
Example:
1 x 160,156,643 = 160,156,643
and
-1 x -160,156,643 = 160,156,643
Notice both answers equal 160,156,643
With that explanation out of the way, let's continue. Next, we take the number 160,156,643 and divide it by 2:
160,156,643 ÷ 2 = 80,078,321.5
If the quotient is a whole number, then 2 and 80,078,321.5 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 | 160,156,643 | |
| -1 | -160,156,643 |
Now, we try dividing 160,156,643 by 3:
160,156,643 ÷ 3 = 53,385,547.6667
If the quotient is a whole number, then 3 and 53,385,547.6667 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 | 160,156,643 | |
| -1 | -160,156,643 |
Let's try dividing by 4:
160,156,643 ÷ 4 = 40,039,160.75
If the quotient is a whole number, then 4 and 40,039,160.75 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 | 160,156,643 | |
| -1 | 160,156,643 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 109 | 323 | 1,853 | 2,071 | 4,549 | 35,207 | 77,333 | 86,431 | 495,841 | 1,469,327 | 8,429,297 | 9,420,979 | 160,156,643 |
| -1 | -17 | -19 | -109 | -323 | -1,853 | -2,071 | -4,549 | -35,207 | -77,333 | -86,431 | -495,841 | -1,469,327 | -8,429,297 | -9,420,979 | -160,156,643 |
