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 1,000,285, 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 | 1,000,285 | |
| -1 | -1,000,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,000,285.
Example:
1 x 1,000,285 = 1,000,285
and
-1 x -1,000,285 = 1,000,285
Notice both answers equal 1,000,285
With that explanation out of the way, let's continue. Next, we take the number 1,000,285 and divide it by 2:
1,000,285 ÷ 2 = 500,142.5
If the quotient is a whole number, then 2 and 500,142.5 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 | 1,000,285 | |
| -1 | -1,000,285 |
Now, we try dividing 1,000,285 by 3:
1,000,285 ÷ 3 = 333,428.3333
If the quotient is a whole number, then 3 and 333,428.3333 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 | 1,000,285 | |
| -1 | -1,000,285 |
Let's try dividing by 4:
1,000,285 ÷ 4 = 250,071.25
If the quotient is a whole number, then 4 and 250,071.25 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 | 1,000,285 | |
| -1 | 1,000,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 1,399 | 6,995 | 15,389 | 18,187 | 76,945 | 90,935 | 200,057 | 1,000,285 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -1,399 | -6,995 | -15,389 | -18,187 | -76,945 | -90,935 | -200,057 | -1,000,285 |
