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 1,560,793, 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 | 1,560,793 | |
| -1 | -1,560,793 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,560,793.
Example:
1 x 1,560,793 = 1,560,793
and
-1 x -1,560,793 = 1,560,793
Notice both answers equal 1,560,793
With that explanation out of the way, let's continue. Next, we take the number 1,560,793 and divide it by 2:
1,560,793 ÷ 2 = 780,396.5
If the quotient is a whole number, then 2 and 780,396.5 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 | 1,560,793 | |
| -1 | -1,560,793 |
Now, we try dividing 1,560,793 by 3:
1,560,793 ÷ 3 = 520,264.3333
If the quotient is a whole number, then 3 and 520,264.3333 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 | 1,560,793 | |
| -1 | -1,560,793 |
Let's try dividing by 4:
1,560,793 ÷ 4 = 390,198.25
If the quotient is a whole number, then 4 and 390,198.25 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 | 1,560,793 | |
| -1 | 1,560,793 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 71 | 89 | 247 | 923 | 1,157 | 1,349 | 1,691 | 6,319 | 17,537 | 21,983 | 82,147 | 120,061 | 1,560,793 |
| -1 | -13 | -19 | -71 | -89 | -247 | -923 | -1,157 | -1,349 | -1,691 | -6,319 | -17,537 | -21,983 | -82,147 | -120,061 | -1,560,793 |
