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 178,267,331, 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 | 178,267,331 | |
| -1 | -178,267,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 178,267,331.
Example:
1 x 178,267,331 = 178,267,331
and
-1 x -178,267,331 = 178,267,331
Notice both answers equal 178,267,331
With that explanation out of the way, let's continue. Next, we take the number 178,267,331 and divide it by 2:
178,267,331 ÷ 2 = 89,133,665.5
If the quotient is a whole number, then 2 and 89,133,665.5 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 | 178,267,331 | |
| -1 | -178,267,331 |
Now, we try dividing 178,267,331 by 3:
178,267,331 ÷ 3 = 59,422,443.6667
If the quotient is a whole number, then 3 and 59,422,443.6667 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 | 178,267,331 | |
| -1 | -178,267,331 |
Let's try dividing by 4:
178,267,331 ÷ 4 = 44,566,832.75
If the quotient is a whole number, then 4 and 44,566,832.75 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 | 178,267,331 | |
| -1 | 178,267,331 |
If you did it right, you will end up with this table:
| 1 | 11 | 113 | 173 | 829 | 1,243 | 1,903 | 9,119 | 19,549 | 93,677 | 143,417 | 215,039 | 1,030,447 | 1,577,587 | 16,206,121 | 178,267,331 |
| -1 | -11 | -113 | -173 | -829 | -1,243 | -1,903 | -9,119 | -19,549 | -93,677 | -143,417 | -215,039 | -1,030,447 | -1,577,587 | -16,206,121 | -178,267,331 |
