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 1,007,545, 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 | 1,007,545 | |
| -1 | -1,007,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,007,545.
Example:
1 x 1,007,545 = 1,007,545
and
-1 x -1,007,545 = 1,007,545
Notice both answers equal 1,007,545
With that explanation out of the way, let's continue. Next, we take the number 1,007,545 and divide it by 2:
1,007,545 ÷ 2 = 503,772.5
If the quotient is a whole number, then 2 and 503,772.5 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 | 1,007,545 | |
| -1 | -1,007,545 |
Now, we try dividing 1,007,545 by 3:
1,007,545 ÷ 3 = 335,848.3333
If the quotient is a whole number, then 3 and 335,848.3333 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 | 1,007,545 | |
| -1 | -1,007,545 |
Let's try dividing by 4:
1,007,545 ÷ 4 = 251,886.25
If the quotient is a whole number, then 4 and 251,886.25 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 | 1,007,545 | |
| -1 | 1,007,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 2,617 | 13,085 | 18,319 | 28,787 | 91,595 | 143,935 | 201,509 | 1,007,545 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -2,617 | -13,085 | -18,319 | -28,787 | -91,595 | -143,935 | -201,509 | -1,007,545 |
