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 2,066,575, 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 | 2,066,575 | |
| -1 | -2,066,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,066,575.
Example:
1 x 2,066,575 = 2,066,575
and
-1 x -2,066,575 = 2,066,575
Notice both answers equal 2,066,575
With that explanation out of the way, let's continue. Next, we take the number 2,066,575 and divide it by 2:
2,066,575 ÷ 2 = 1,033,287.5
If the quotient is a whole number, then 2 and 1,033,287.5 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 | 2,066,575 | |
| -1 | -2,066,575 |
Now, we try dividing 2,066,575 by 3:
2,066,575 ÷ 3 = 688,858.3333
If the quotient is a whole number, then 3 and 688,858.3333 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 | 2,066,575 | |
| -1 | -2,066,575 |
Let's try dividing by 4:
2,066,575 ÷ 4 = 516,643.75
If the quotient is a whole number, then 4 and 516,643.75 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 | 2,066,575 | |
| -1 | 2,066,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 241 | 245 | 343 | 1,205 | 1,225 | 1,687 | 1,715 | 6,025 | 8,435 | 8,575 | 11,809 | 42,175 | 59,045 | 82,663 | 295,225 | 413,315 | 2,066,575 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -241 | -245 | -343 | -1,205 | -1,225 | -1,687 | -1,715 | -6,025 | -8,435 | -8,575 | -11,809 | -42,175 | -59,045 | -82,663 | -295,225 | -413,315 | -2,066,575 |
