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 1,637,935, 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 | 1,637,935 | |
| -1 | -1,637,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,637,935.
Example:
1 x 1,637,935 = 1,637,935
and
-1 x -1,637,935 = 1,637,935
Notice both answers equal 1,637,935
With that explanation out of the way, let's continue. Next, we take the number 1,637,935 and divide it by 2:
1,637,935 ÷ 2 = 818,967.5
If the quotient is a whole number, then 2 and 818,967.5 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 | 1,637,935 | |
| -1 | -1,637,935 |
Now, we try dividing 1,637,935 by 3:
1,637,935 ÷ 3 = 545,978.3333
If the quotient is a whole number, then 3 and 545,978.3333 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 | 1,637,935 | |
| -1 | -1,637,935 |
Let's try dividing by 4:
1,637,935 ÷ 4 = 409,483.75
If the quotient is a whole number, then 4 and 409,483.75 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 | 1,637,935 | |
| -1 | 1,637,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 113 | 223 | 565 | 1,115 | 1,469 | 2,899 | 7,345 | 14,495 | 25,199 | 125,995 | 327,587 | 1,637,935 |
| -1 | -5 | -13 | -65 | -113 | -223 | -565 | -1,115 | -1,469 | -2,899 | -7,345 | -14,495 | -25,199 | -125,995 | -327,587 | -1,637,935 |
