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 173,738,477, 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 | 173,738,477 | |
| -1 | -173,738,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,738,477.
Example:
1 x 173,738,477 = 173,738,477
and
-1 x -173,738,477 = 173,738,477
Notice both answers equal 173,738,477
With that explanation out of the way, let's continue. Next, we take the number 173,738,477 and divide it by 2:
173,738,477 ÷ 2 = 86,869,238.5
If the quotient is a whole number, then 2 and 86,869,238.5 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 | 173,738,477 | |
| -1 | -173,738,477 |
Now, we try dividing 173,738,477 by 3:
173,738,477 ÷ 3 = 57,912,825.6667
If the quotient is a whole number, then 3 and 57,912,825.6667 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 | 173,738,477 | |
| -1 | -173,738,477 |
Let's try dividing by 4:
173,738,477 ÷ 4 = 43,434,619.25
If the quotient is a whole number, then 4 and 43,434,619.25 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 | 173,738,477 | |
| -1 | 173,738,477 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 341 | 467 | 1,091 | 5,137 | 12,001 | 14,477 | 33,821 | 159,247 | 372,031 | 509,497 | 5,604,467 | 15,794,407 | 173,738,477 |
| -1 | -11 | -31 | -341 | -467 | -1,091 | -5,137 | -12,001 | -14,477 | -33,821 | -159,247 | -372,031 | -509,497 | -5,604,467 | -15,794,407 | -173,738,477 |
