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 1,685,453, 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 | 1,685,453 | |
| -1 | -1,685,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,685,453.
Example:
1 x 1,685,453 = 1,685,453
and
-1 x -1,685,453 = 1,685,453
Notice both answers equal 1,685,453
With that explanation out of the way, let's continue. Next, we take the number 1,685,453 and divide it by 2:
1,685,453 ÷ 2 = 842,726.5
If the quotient is a whole number, then 2 and 842,726.5 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 | 1,685,453 | |
| -1 | -1,685,453 |
Now, we try dividing 1,685,453 by 3:
1,685,453 ÷ 3 = 561,817.6667
If the quotient is a whole number, then 3 and 561,817.6667 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 | 1,685,453 | |
| -1 | -1,685,453 |
Let's try dividing by 4:
1,685,453 ÷ 4 = 421,363.25
If the quotient is a whole number, then 4 and 421,363.25 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 | 1,685,453 | |
| -1 | 1,685,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 53 | 59 | 77 | 371 | 413 | 539 | 583 | 649 | 2,597 | 2,891 | 3,127 | 4,081 | 4,543 | 21,889 | 28,567 | 31,801 | 34,397 | 153,223 | 240,779 | 1,685,453 |
| -1 | -7 | -11 | -49 | -53 | -59 | -77 | -371 | -413 | -539 | -583 | -649 | -2,597 | -2,891 | -3,127 | -4,081 | -4,543 | -21,889 | -28,567 | -31,801 | -34,397 | -153,223 | -240,779 | -1,685,453 |
