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 160,611,529, 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 | 160,611,529 | |
| -1 | -160,611,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,611,529.
Example:
1 x 160,611,529 = 160,611,529
and
-1 x -160,611,529 = 160,611,529
Notice both answers equal 160,611,529
With that explanation out of the way, let's continue. Next, we take the number 160,611,529 and divide it by 2:
160,611,529 ÷ 2 = 80,305,764.5
If the quotient is a whole number, then 2 and 80,305,764.5 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 | 160,611,529 | |
| -1 | -160,611,529 |
Now, we try dividing 160,611,529 by 3:
160,611,529 ÷ 3 = 53,537,176.3333
If the quotient is a whole number, then 3 and 53,537,176.3333 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 | 160,611,529 | |
| -1 | -160,611,529 |
Let's try dividing by 4:
160,611,529 ÷ 4 = 40,152,882.25
If the quotient is a whole number, then 4 and 40,152,882.25 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 | 160,611,529 | |
| -1 | 160,611,529 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 67 | 221 | 871 | 1,139 | 10,847 | 14,807 | 141,011 | 184,399 | 726,749 | 2,397,187 | 9,447,737 | 12,354,733 | 160,611,529 |
| -1 | -13 | -17 | -67 | -221 | -871 | -1,139 | -10,847 | -14,807 | -141,011 | -184,399 | -726,749 | -2,397,187 | -9,447,737 | -12,354,733 | -160,611,529 |
