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 167,316,023, 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 | 167,316,023 | |
| -1 | -167,316,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,316,023.
Example:
1 x 167,316,023 = 167,316,023
and
-1 x -167,316,023 = 167,316,023
Notice both answers equal 167,316,023
With that explanation out of the way, let's continue. Next, we take the number 167,316,023 and divide it by 2:
167,316,023 ÷ 2 = 83,658,011.5
If the quotient is a whole number, then 2 and 83,658,011.5 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 | 167,316,023 | |
| -1 | -167,316,023 |
Now, we try dividing 167,316,023 by 3:
167,316,023 ÷ 3 = 55,772,007.6667
If the quotient is a whole number, then 3 and 55,772,007.6667 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 | 167,316,023 | |
| -1 | -167,316,023 |
Let's try dividing by 4:
167,316,023 ÷ 4 = 41,829,005.75
If the quotient is a whole number, then 4 and 41,829,005.75 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 | 167,316,023 | |
| -1 | 167,316,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 127 | 889 | 2,159 | 11,071 | 15,113 | 77,497 | 188,207 | 1,317,449 | 1,406,017 | 9,842,119 | 23,902,289 | 167,316,023 |
| -1 | -7 | -17 | -119 | -127 | -889 | -2,159 | -11,071 | -15,113 | -77,497 | -188,207 | -1,317,449 | -1,406,017 | -9,842,119 | -23,902,289 | -167,316,023 |
