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 1,801,735, 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 | 1,801,735 | |
| -1 | -1,801,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,801,735.
Example:
1 x 1,801,735 = 1,801,735
and
-1 x -1,801,735 = 1,801,735
Notice both answers equal 1,801,735
With that explanation out of the way, let's continue. Next, we take the number 1,801,735 and divide it by 2:
1,801,735 ÷ 2 = 900,867.5
If the quotient is a whole number, then 2 and 900,867.5 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 | 1,801,735 | |
| -1 | -1,801,735 |
Now, we try dividing 1,801,735 by 3:
1,801,735 ÷ 3 = 600,578.3333
If the quotient is a whole number, then 3 and 600,578.3333 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 | 1,801,735 | |
| -1 | -1,801,735 |
Let's try dividing by 4:
1,801,735 ÷ 4 = 450,433.75
If the quotient is a whole number, then 4 and 450,433.75 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 | 1,801,735 | |
| -1 | 1,801,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 53 | 65 | 265 | 523 | 689 | 2,615 | 3,445 | 6,799 | 27,719 | 33,995 | 138,595 | 360,347 | 1,801,735 |
| -1 | -5 | -13 | -53 | -65 | -265 | -523 | -689 | -2,615 | -3,445 | -6,799 | -27,719 | -33,995 | -138,595 | -360,347 | -1,801,735 |
