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 1,722,205, 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 | 1,722,205 | |
| -1 | -1,722,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,722,205.
Example:
1 x 1,722,205 = 1,722,205
and
-1 x -1,722,205 = 1,722,205
Notice both answers equal 1,722,205
With that explanation out of the way, let's continue. Next, we take the number 1,722,205 and divide it by 2:
1,722,205 ÷ 2 = 861,102.5
If the quotient is a whole number, then 2 and 861,102.5 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 | 1,722,205 | |
| -1 | -1,722,205 |
Now, we try dividing 1,722,205 by 3:
1,722,205 ÷ 3 = 574,068.3333
If the quotient is a whole number, then 3 and 574,068.3333 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 | 1,722,205 | |
| -1 | -1,722,205 |
Let's try dividing by 4:
1,722,205 ÷ 4 = 430,551.25
If the quotient is a whole number, then 4 and 430,551.25 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 | 1,722,205 | |
| -1 | 1,722,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 41 | 155 | 205 | 271 | 1,271 | 1,355 | 6,355 | 8,401 | 11,111 | 42,005 | 55,555 | 344,441 | 1,722,205 |
| -1 | -5 | -31 | -41 | -155 | -205 | -271 | -1,271 | -1,355 | -6,355 | -8,401 | -11,111 | -42,005 | -55,555 | -344,441 | -1,722,205 |
