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 1,559,155, 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 | 1,559,155 | |
| -1 | -1,559,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,559,155.
Example:
1 x 1,559,155 = 1,559,155
and
-1 x -1,559,155 = 1,559,155
Notice both answers equal 1,559,155
With that explanation out of the way, let's continue. Next, we take the number 1,559,155 and divide it by 2:
1,559,155 ÷ 2 = 779,577.5
If the quotient is a whole number, then 2 and 779,577.5 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 | 1,559,155 | |
| -1 | -1,559,155 |
Now, we try dividing 1,559,155 by 3:
1,559,155 ÷ 3 = 519,718.3333
If the quotient is a whole number, then 3 and 519,718.3333 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 | 1,559,155 | |
| -1 | -1,559,155 |
Let's try dividing by 4:
1,559,155 ÷ 4 = 389,788.75
If the quotient is a whole number, then 4 and 389,788.75 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 | 1,559,155 | |
| -1 | 1,559,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 83 | 85 | 221 | 289 | 415 | 1,079 | 1,105 | 1,411 | 1,445 | 3,757 | 5,395 | 7,055 | 18,343 | 18,785 | 23,987 | 91,715 | 119,935 | 311,831 | 1,559,155 |
| -1 | -5 | -13 | -17 | -65 | -83 | -85 | -221 | -289 | -415 | -1,079 | -1,105 | -1,411 | -1,445 | -3,757 | -5,395 | -7,055 | -18,343 | -18,785 | -23,987 | -91,715 | -119,935 | -311,831 | -1,559,155 |
