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 1,785,745, 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 | 1,785,745 | |
| -1 | -1,785,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,785,745.
Example:
1 x 1,785,745 = 1,785,745
and
-1 x -1,785,745 = 1,785,745
Notice both answers equal 1,785,745
With that explanation out of the way, let's continue. Next, we take the number 1,785,745 and divide it by 2:
1,785,745 ÷ 2 = 892,872.5
If the quotient is a whole number, then 2 and 892,872.5 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 | 1,785,745 | |
| -1 | -1,785,745 |
Now, we try dividing 1,785,745 by 3:
1,785,745 ÷ 3 = 595,248.3333
If the quotient is a whole number, then 3 and 595,248.3333 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 | 1,785,745 | |
| -1 | -1,785,745 |
Let's try dividing by 4:
1,785,745 ÷ 4 = 446,436.25
If the quotient is a whole number, then 4 and 446,436.25 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 | 1,785,745 | |
| -1 | 1,785,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 83 | 331 | 415 | 1,079 | 1,655 | 4,303 | 5,395 | 21,515 | 27,473 | 137,365 | 357,149 | 1,785,745 |
| -1 | -5 | -13 | -65 | -83 | -331 | -415 | -1,079 | -1,655 | -4,303 | -5,395 | -21,515 | -27,473 | -137,365 | -357,149 | -1,785,745 |
