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 176,667,647, 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 | 176,667,647 | |
| -1 | -176,667,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,667,647.
Example:
1 x 176,667,647 = 176,667,647
and
-1 x -176,667,647 = 176,667,647
Notice both answers equal 176,667,647
With that explanation out of the way, let's continue. Next, we take the number 176,667,647 and divide it by 2:
176,667,647 ÷ 2 = 88,333,823.5
If the quotient is a whole number, then 2 and 88,333,823.5 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 | 176,667,647 | |
| -1 | -176,667,647 |
Now, we try dividing 176,667,647 by 3:
176,667,647 ÷ 3 = 58,889,215.6667
If the quotient is a whole number, then 3 and 58,889,215.6667 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 | 176,667,647 | |
| -1 | -176,667,647 |
Let's try dividing by 4:
176,667,647 ÷ 4 = 44,166,911.75
If the quotient is a whole number, then 4 and 44,166,911.75 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 | 176,667,647 | |
| -1 | 176,667,647 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 461 | 533 | 719 | 5,993 | 9,347 | 18,901 | 29,479 | 245,713 | 331,459 | 383,227 | 4,308,967 | 13,589,819 | 176,667,647 |
| -1 | -13 | -41 | -461 | -533 | -719 | -5,993 | -9,347 | -18,901 | -29,479 | -245,713 | -331,459 | -383,227 | -4,308,967 | -13,589,819 | -176,667,647 |
