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 1,579,045, 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 | 1,579,045 | |
| -1 | -1,579,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,579,045.
Example:
1 x 1,579,045 = 1,579,045
and
-1 x -1,579,045 = 1,579,045
Notice both answers equal 1,579,045
With that explanation out of the way, let's continue. Next, we take the number 1,579,045 and divide it by 2:
1,579,045 ÷ 2 = 789,522.5
If the quotient is a whole number, then 2 and 789,522.5 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 | 1,579,045 | |
| -1 | -1,579,045 |
Now, we try dividing 1,579,045 by 3:
1,579,045 ÷ 3 = 526,348.3333
If the quotient is a whole number, then 3 and 526,348.3333 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 | 1,579,045 | |
| -1 | -1,579,045 |
Let's try dividing by 4:
1,579,045 ÷ 4 = 394,761.25
If the quotient is a whole number, then 4 and 394,761.25 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 | 1,579,045 | |
| -1 | 1,579,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 1,429 | 7,145 | 18,577 | 24,293 | 92,885 | 121,465 | 315,809 | 1,579,045 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -1,429 | -7,145 | -18,577 | -24,293 | -92,885 | -121,465 | -315,809 | -1,579,045 |
