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 179,560,205, 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 | 179,560,205 | |
| -1 | -179,560,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 179,560,205.
Example:
1 x 179,560,205 = 179,560,205
and
-1 x -179,560,205 = 179,560,205
Notice both answers equal 179,560,205
With that explanation out of the way, let's continue. Next, we take the number 179,560,205 and divide it by 2:
179,560,205 ÷ 2 = 89,780,102.5
If the quotient is a whole number, then 2 and 89,780,102.5 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 | 179,560,205 | |
| -1 | -179,560,205 |
Now, we try dividing 179,560,205 by 3:
179,560,205 ÷ 3 = 59,853,401.6667
If the quotient is a whole number, then 3 and 59,853,401.6667 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 | 179,560,205 | |
| -1 | -179,560,205 |
Let's try dividing by 4:
179,560,205 ÷ 4 = 44,890,051.25
If the quotient is a whole number, then 4 and 44,890,051.25 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 | 179,560,205 | |
| -1 | 179,560,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 192,043 | 960,215 | 2,112,473 | 3,264,731 | 10,562,365 | 16,323,655 | 35,912,041 | 179,560,205 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -192,043 | -960,215 | -2,112,473 | -3,264,731 | -10,562,365 | -16,323,655 | -35,912,041 | -179,560,205 |
