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 1,798,435, 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 | 1,798,435 | |
| -1 | -1,798,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,798,435.
Example:
1 x 1,798,435 = 1,798,435
and
-1 x -1,798,435 = 1,798,435
Notice both answers equal 1,798,435
With that explanation out of the way, let's continue. Next, we take the number 1,798,435 and divide it by 2:
1,798,435 ÷ 2 = 899,217.5
If the quotient is a whole number, then 2 and 899,217.5 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 | 1,798,435 | |
| -1 | -1,798,435 |
Now, we try dividing 1,798,435 by 3:
1,798,435 ÷ 3 = 599,478.3333
If the quotient is a whole number, then 3 and 599,478.3333 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 | 1,798,435 | |
| -1 | -1,798,435 |
Let's try dividing by 4:
1,798,435 ÷ 4 = 449,608.75
If the quotient is a whole number, then 4 and 449,608.75 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 | 1,798,435 | |
| -1 | 1,798,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 79 | 145 | 157 | 395 | 785 | 2,291 | 4,553 | 11,455 | 12,403 | 22,765 | 62,015 | 359,687 | 1,798,435 |
| -1 | -5 | -29 | -79 | -145 | -157 | -395 | -785 | -2,291 | -4,553 | -11,455 | -12,403 | -22,765 | -62,015 | -359,687 | -1,798,435 |
