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 1,566,037, 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 | 1,566,037 | |
| -1 | -1,566,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,566,037.
Example:
1 x 1,566,037 = 1,566,037
and
-1 x -1,566,037 = 1,566,037
Notice both answers equal 1,566,037
With that explanation out of the way, let's continue. Next, we take the number 1,566,037 and divide it by 2:
1,566,037 ÷ 2 = 783,018.5
If the quotient is a whole number, then 2 and 783,018.5 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 | 1,566,037 | |
| -1 | -1,566,037 |
Now, we try dividing 1,566,037 by 3:
1,566,037 ÷ 3 = 522,012.3333
If the quotient is a whole number, then 3 and 522,012.3333 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 | 1,566,037 | |
| -1 | -1,566,037 |
Let's try dividing by 4:
1,566,037 ÷ 4 = 391,509.25
If the quotient is a whole number, then 4 and 391,509.25 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 | 1,566,037 | |
| -1 | 1,566,037 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 59 | 127 | 209 | 649 | 1,121 | 1,397 | 2,413 | 7,493 | 12,331 | 26,543 | 82,423 | 142,367 | 1,566,037 |
| -1 | -11 | -19 | -59 | -127 | -209 | -649 | -1,121 | -1,397 | -2,413 | -7,493 | -12,331 | -26,543 | -82,423 | -142,367 | -1,566,037 |
