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 167,351,489, 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 | 167,351,489 | |
| -1 | -167,351,489 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,351,489.
Example:
1 x 167,351,489 = 167,351,489
and
-1 x -167,351,489 = 167,351,489
Notice both answers equal 167,351,489
With that explanation out of the way, let's continue. Next, we take the number 167,351,489 and divide it by 2:
167,351,489 ÷ 2 = 83,675,744.5
If the quotient is a whole number, then 2 and 83,675,744.5 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 | 167,351,489 | |
| -1 | -167,351,489 |
Now, we try dividing 167,351,489 by 3:
167,351,489 ÷ 3 = 55,783,829.6667
If the quotient is a whole number, then 3 and 55,783,829.6667 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 | 167,351,489 | |
| -1 | -167,351,489 |
Let's try dividing by 4:
167,351,489 ÷ 4 = 41,837,872.25
If the quotient is a whole number, then 4 and 41,837,872.25 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 | 167,351,489 | |
| -1 | 167,351,489 |
If you did it right, you will end up with this table:
| 1 | 29 | 83 | 251 | 277 | 2,407 | 7,279 | 8,033 | 20,833 | 22,991 | 69,527 | 604,157 | 666,739 | 2,016,283 | 5,770,741 | 167,351,489 |
| -1 | -29 | -83 | -251 | -277 | -2,407 | -7,279 | -8,033 | -20,833 | -22,991 | -69,527 | -604,157 | -666,739 | -2,016,283 | -5,770,741 | -167,351,489 |
