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 1,560,559, 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 | 1,560,559 | |
| -1 | -1,560,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,560,559.
Example:
1 x 1,560,559 = 1,560,559
and
-1 x -1,560,559 = 1,560,559
Notice both answers equal 1,560,559
With that explanation out of the way, let's continue. Next, we take the number 1,560,559 and divide it by 2:
1,560,559 ÷ 2 = 780,279.5
If the quotient is a whole number, then 2 and 780,279.5 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 | 1,560,559 | |
| -1 | -1,560,559 |
Now, we try dividing 1,560,559 by 3:
1,560,559 ÷ 3 = 520,186.3333
If the quotient is a whole number, then 3 and 520,186.3333 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 | 1,560,559 | |
| -1 | -1,560,559 |
Let's try dividing by 4:
1,560,559 ÷ 4 = 390,139.75
If the quotient is a whole number, then 4 and 390,139.75 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 | 1,560,559 | |
| -1 | 1,560,559 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 1,559 | 10,913 | 17,149 | 20,267 | 120,043 | 141,869 | 222,937 | 1,560,559 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -1,559 | -10,913 | -17,149 | -20,267 | -120,043 | -141,869 | -222,937 | -1,560,559 |
