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 176,210,705, 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 | 176,210,705 | |
| -1 | -176,210,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,210,705.
Example:
1 x 176,210,705 = 176,210,705
and
-1 x -176,210,705 = 176,210,705
Notice both answers equal 176,210,705
With that explanation out of the way, let's continue. Next, we take the number 176,210,705 and divide it by 2:
176,210,705 ÷ 2 = 88,105,352.5
If the quotient is a whole number, then 2 and 88,105,352.5 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 | 176,210,705 | |
| -1 | -176,210,705 |
Now, we try dividing 176,210,705 by 3:
176,210,705 ÷ 3 = 58,736,901.6667
If the quotient is a whole number, then 3 and 58,736,901.6667 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 | 176,210,705 | |
| -1 | -176,210,705 |
Let's try dividing by 4:
176,210,705 ÷ 4 = 44,052,676.25
If the quotient is a whole number, then 4 and 44,052,676.25 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 | 176,210,705 | |
| -1 | 176,210,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 139,297 | 696,485 | 1,532,267 | 3,203,831 | 7,661,335 | 16,019,155 | 35,242,141 | 176,210,705 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -139,297 | -696,485 | -1,532,267 | -3,203,831 | -7,661,335 | -16,019,155 | -35,242,141 | -176,210,705 |
