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 1,566,839, 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 | 1,566,839 | |
| -1 | -1,566,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,566,839.
Example:
1 x 1,566,839 = 1,566,839
and
-1 x -1,566,839 = 1,566,839
Notice both answers equal 1,566,839
With that explanation out of the way, let's continue. Next, we take the number 1,566,839 and divide it by 2:
1,566,839 ÷ 2 = 783,419.5
If the quotient is a whole number, then 2 and 783,419.5 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 | 1,566,839 | |
| -1 | -1,566,839 |
Now, we try dividing 1,566,839 by 3:
1,566,839 ÷ 3 = 522,279.6667
If the quotient is a whole number, then 3 and 522,279.6667 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 | 1,566,839 | |
| -1 | -1,566,839 |
Let's try dividing by 4:
1,566,839 ÷ 4 = 391,709.75
If the quotient is a whole number, then 4 and 391,709.75 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 | 1,566,839 | |
| -1 | 1,566,839 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 47 | 53 | 629 | 799 | 901 | 1,739 | 1,961 | 2,491 | 29,563 | 33,337 | 42,347 | 92,167 | 1,566,839 |
| -1 | -17 | -37 | -47 | -53 | -629 | -799 | -901 | -1,739 | -1,961 | -2,491 | -29,563 | -33,337 | -42,347 | -92,167 | -1,566,839 |
