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 176,028,749, 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 | 176,028,749 | |
| -1 | -176,028,749 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,028,749.
Example:
1 x 176,028,749 = 176,028,749
and
-1 x -176,028,749 = 176,028,749
Notice both answers equal 176,028,749
With that explanation out of the way, let's continue. Next, we take the number 176,028,749 and divide it by 2:
176,028,749 ÷ 2 = 88,014,374.5
If the quotient is a whole number, then 2 and 88,014,374.5 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 | 176,028,749 | |
| -1 | -176,028,749 |
Now, we try dividing 176,028,749 by 3:
176,028,749 ÷ 3 = 58,676,249.6667
If the quotient is a whole number, then 3 and 58,676,249.6667 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 | 176,028,749 | |
| -1 | -176,028,749 |
Let's try dividing by 4:
176,028,749 ÷ 4 = 44,007,187.25
If the quotient is a whole number, then 4 and 44,007,187.25 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 | 176,028,749 | |
| -1 | 176,028,749 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 149 | 247 | 1,937 | 2,831 | 4,783 | 36,803 | 62,179 | 90,877 | 712,667 | 1,181,401 | 9,264,671 | 13,540,673 | 176,028,749 |
| -1 | -13 | -19 | -149 | -247 | -1,937 | -2,831 | -4,783 | -36,803 | -62,179 | -90,877 | -712,667 | -1,181,401 | -9,264,671 | -13,540,673 | -176,028,749 |
