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 1,790,393, 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 | 1,790,393 | |
| -1 | -1,790,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,790,393.
Example:
1 x 1,790,393 = 1,790,393
and
-1 x -1,790,393 = 1,790,393
Notice both answers equal 1,790,393
With that explanation out of the way, let's continue. Next, we take the number 1,790,393 and divide it by 2:
1,790,393 ÷ 2 = 895,196.5
If the quotient is a whole number, then 2 and 895,196.5 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 | 1,790,393 | |
| -1 | -1,790,393 |
Now, we try dividing 1,790,393 by 3:
1,790,393 ÷ 3 = 596,797.6667
If the quotient is a whole number, then 3 and 596,797.6667 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 | 1,790,393 | |
| -1 | -1,790,393 |
Let's try dividing by 4:
1,790,393 ÷ 4 = 447,598.25
If the quotient is a whole number, then 4 and 447,598.25 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 | 1,790,393 | |
| -1 | 1,790,393 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 53 | 83 | 407 | 583 | 913 | 1,961 | 3,071 | 4,399 | 21,571 | 33,781 | 48,389 | 162,763 | 1,790,393 |
| -1 | -11 | -37 | -53 | -83 | -407 | -583 | -913 | -1,961 | -3,071 | -4,399 | -21,571 | -33,781 | -48,389 | -162,763 | -1,790,393 |
