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 1,745,425, 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 | 1,745,425 | |
| -1 | -1,745,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,745,425.
Example:
1 x 1,745,425 = 1,745,425
and
-1 x -1,745,425 = 1,745,425
Notice both answers equal 1,745,425
With that explanation out of the way, let's continue. Next, we take the number 1,745,425 and divide it by 2:
1,745,425 ÷ 2 = 872,712.5
If the quotient is a whole number, then 2 and 872,712.5 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 | 1,745,425 | |
| -1 | -1,745,425 |
Now, we try dividing 1,745,425 by 3:
1,745,425 ÷ 3 = 581,808.3333
If the quotient is a whole number, then 3 and 581,808.3333 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 | 1,745,425 | |
| -1 | -1,745,425 |
Let's try dividing by 4:
1,745,425 ÷ 4 = 436,356.25
If the quotient is a whole number, then 4 and 436,356.25 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 | 1,745,425 | |
| -1 | 1,745,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 577 | 605 | 2,885 | 3,025 | 6,347 | 14,425 | 31,735 | 69,817 | 158,675 | 349,085 | 1,745,425 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -577 | -605 | -2,885 | -3,025 | -6,347 | -14,425 | -31,735 | -69,817 | -158,675 | -349,085 | -1,745,425 |
