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 785,323, 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 | 785,323 | |
| -1 | -785,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 785,323.
Example:
1 x 785,323 = 785,323
and
-1 x -785,323 = 785,323
Notice both answers equal 785,323
With that explanation out of the way, let's continue. Next, we take the number 785,323 and divide it by 2:
785,323 ÷ 2 = 392,661.5
If the quotient is a whole number, then 2 and 392,661.5 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 | 785,323 | |
| -1 | -785,323 |
Now, we try dividing 785,323 by 3:
785,323 ÷ 3 = 261,774.3333
If the quotient is a whole number, then 3 and 261,774.3333 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 | 785,323 | |
| -1 | -785,323 |
Let's try dividing by 4:
785,323 ÷ 4 = 196,330.75
If the quotient is a whole number, then 4 and 196,330.75 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 | 785,323 | |
| -1 | 785,323 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 47 | 49 | 77 | 217 | 329 | 341 | 517 | 539 | 1,457 | 1,519 | 2,303 | 2,387 | 3,619 | 10,199 | 16,027 | 16,709 | 25,333 | 71,393 | 112,189 | 785,323 |
| -1 | -7 | -11 | -31 | -47 | -49 | -77 | -217 | -329 | -341 | -517 | -539 | -1,457 | -1,519 | -2,303 | -2,387 | -3,619 | -10,199 | -16,027 | -16,709 | -25,333 | -71,393 | -112,189 | -785,323 |
