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 177,741,403, 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 | 177,741,403 | |
| -1 | -177,741,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,741,403.
Example:
1 x 177,741,403 = 177,741,403
and
-1 x -177,741,403 = 177,741,403
Notice both answers equal 177,741,403
With that explanation out of the way, let's continue. Next, we take the number 177,741,403 and divide it by 2:
177,741,403 ÷ 2 = 88,870,701.5
If the quotient is a whole number, then 2 and 88,870,701.5 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 | 177,741,403 | |
| -1 | -177,741,403 |
Now, we try dividing 177,741,403 by 3:
177,741,403 ÷ 3 = 59,247,134.3333
If the quotient is a whole number, then 3 and 59,247,134.3333 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 | 177,741,403 | |
| -1 | -177,741,403 |
Let's try dividing by 4:
177,741,403 ÷ 4 = 44,435,350.75
If the quotient is a whole number, then 4 and 44,435,350.75 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 | 177,741,403 | |
| -1 | 177,741,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 301 | 367 | 1,609 | 2,569 | 11,263 | 15,781 | 69,187 | 110,467 | 484,309 | 590,503 | 4,133,521 | 25,391,629 | 177,741,403 |
| -1 | -7 | -43 | -301 | -367 | -1,609 | -2,569 | -11,263 | -15,781 | -69,187 | -110,467 | -484,309 | -590,503 | -4,133,521 | -25,391,629 | -177,741,403 |
