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 177,594,131, 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 | 177,594,131 | |
| -1 | -177,594,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,594,131.
Example:
1 x 177,594,131 = 177,594,131
and
-1 x -177,594,131 = 177,594,131
Notice both answers equal 177,594,131
With that explanation out of the way, let's continue. Next, we take the number 177,594,131 and divide it by 2:
177,594,131 ÷ 2 = 88,797,065.5
If the quotient is a whole number, then 2 and 88,797,065.5 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 | 177,594,131 | |
| -1 | -177,594,131 |
Now, we try dividing 177,594,131 by 3:
177,594,131 ÷ 3 = 59,198,043.6667
If the quotient is a whole number, then 3 and 59,198,043.6667 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 | 177,594,131 | |
| -1 | -177,594,131 |
Let's try dividing by 4:
177,594,131 ÷ 4 = 44,398,532.75
If the quotient is a whole number, then 4 and 44,398,532.75 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 | 177,594,131 | |
| -1 | 177,594,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 227 | 2,497 | 2,951 | 5,471 | 32,461 | 60,181 | 71,123 | 782,353 | 1,241,917 | 13,661,087 | 16,144,921 | 177,594,131 |
| -1 | -11 | -13 | -143 | -227 | -2,497 | -2,951 | -5,471 | -32,461 | -60,181 | -71,123 | -782,353 | -1,241,917 | -13,661,087 | -16,144,921 | -177,594,131 |
