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 160,767,061, 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 | 160,767,061 | |
| -1 | -160,767,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,767,061.
Example:
1 x 160,767,061 = 160,767,061
and
-1 x -160,767,061 = 160,767,061
Notice both answers equal 160,767,061
With that explanation out of the way, let's continue. Next, we take the number 160,767,061 and divide it by 2:
160,767,061 ÷ 2 = 80,383,530.5
If the quotient is a whole number, then 2 and 80,383,530.5 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 | 160,767,061 | |
| -1 | -160,767,061 |
Now, we try dividing 160,767,061 by 3:
160,767,061 ÷ 3 = 53,589,020.3333
If the quotient is a whole number, then 3 and 53,589,020.3333 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 | 160,767,061 | |
| -1 | -160,767,061 |
Let's try dividing by 4:
160,767,061 ÷ 4 = 40,191,765.25
If the quotient is a whole number, then 4 and 40,191,765.25 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 | 160,767,061 | |
| -1 | 160,767,061 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 1,201 | 1,471 | 8,407 | 10,297 | 15,613 | 19,123 | 109,291 | 133,861 | 1,766,671 | 12,366,697 | 22,966,723 | 160,767,061 |
| -1 | -7 | -13 | -91 | -1,201 | -1,471 | -8,407 | -10,297 | -15,613 | -19,123 | -109,291 | -133,861 | -1,766,671 | -12,366,697 | -22,966,723 | -160,767,061 |
