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 178,111,265, 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 | 178,111,265 | |
| -1 | -178,111,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 178,111,265.
Example:
1 x 178,111,265 = 178,111,265
and
-1 x -178,111,265 = 178,111,265
Notice both answers equal 178,111,265
With that explanation out of the way, let's continue. Next, we take the number 178,111,265 and divide it by 2:
178,111,265 ÷ 2 = 89,055,632.5
If the quotient is a whole number, then 2 and 89,055,632.5 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 | 178,111,265 | |
| -1 | -178,111,265 |
Now, we try dividing 178,111,265 by 3:
178,111,265 ÷ 3 = 59,370,421.6667
If the quotient is a whole number, then 3 and 59,370,421.6667 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 | 178,111,265 | |
| -1 | -178,111,265 |
Let's try dividing by 4:
178,111,265 ÷ 4 = 44,527,816.25
If the quotient is a whole number, then 4 and 44,527,816.25 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 | 178,111,265 | |
| -1 | 178,111,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 179 | 295 | 895 | 3,373 | 10,561 | 16,865 | 52,805 | 199,007 | 603,767 | 995,035 | 3,018,835 | 35,622,253 | 178,111,265 |
| -1 | -5 | -59 | -179 | -295 | -895 | -3,373 | -10,561 | -16,865 | -52,805 | -199,007 | -603,767 | -995,035 | -3,018,835 | -35,622,253 | -178,111,265 |
