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 167,730,233, 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 | 167,730,233 | |
| -1 | -167,730,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,730,233.
Example:
1 x 167,730,233 = 167,730,233
and
-1 x -167,730,233 = 167,730,233
Notice both answers equal 167,730,233
With that explanation out of the way, let's continue. Next, we take the number 167,730,233 and divide it by 2:
167,730,233 ÷ 2 = 83,865,116.5
If the quotient is a whole number, then 2 and 83,865,116.5 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 | 167,730,233 | |
| -1 | -167,730,233 |
Now, we try dividing 167,730,233 by 3:
167,730,233 ÷ 3 = 55,910,077.6667
If the quotient is a whole number, then 3 and 55,910,077.6667 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 | 167,730,233 | |
| -1 | -167,730,233 |
Let's try dividing by 4:
167,730,233 ÷ 4 = 41,932,558.25
If the quotient is a whole number, then 4 and 41,932,558.25 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 | 167,730,233 | |
| -1 | 167,730,233 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 209 | 653 | 1,229 | 7,183 | 12,407 | 13,519 | 23,351 | 136,477 | 256,861 | 802,537 | 8,827,907 | 15,248,203 | 167,730,233 |
| -1 | -11 | -19 | -209 | -653 | -1,229 | -7,183 | -12,407 | -13,519 | -23,351 | -136,477 | -256,861 | -802,537 | -8,827,907 | -15,248,203 | -167,730,233 |
