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 160,110,433, 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 | 160,110,433 | |
| -1 | -160,110,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,110,433.
Example:
1 x 160,110,433 = 160,110,433
and
-1 x -160,110,433 = 160,110,433
Notice both answers equal 160,110,433
With that explanation out of the way, let's continue. Next, we take the number 160,110,433 and divide it by 2:
160,110,433 ÷ 2 = 80,055,216.5
If the quotient is a whole number, then 2 and 80,055,216.5 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 | 160,110,433 | |
| -1 | -160,110,433 |
Now, we try dividing 160,110,433 by 3:
160,110,433 ÷ 3 = 53,370,144.3333
If the quotient is a whole number, then 3 and 53,370,144.3333 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 | 160,110,433 | |
| -1 | -160,110,433 |
Let's try dividing by 4:
160,110,433 ÷ 4 = 40,027,608.25
If the quotient is a whole number, then 4 and 40,027,608.25 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 | 160,110,433 | |
| -1 | 160,110,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 503 | 1,229 | 3,521 | 8,603 | 18,611 | 45,473 | 130,277 | 318,311 | 618,187 | 4,327,309 | 22,872,919 | 160,110,433 |
| -1 | -7 | -37 | -259 | -503 | -1,229 | -3,521 | -8,603 | -18,611 | -45,473 | -130,277 | -318,311 | -618,187 | -4,327,309 | -22,872,919 | -160,110,433 |
