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 1,002,115, 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 | 1,002,115 | |
| -1 | -1,002,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,002,115.
Example:
1 x 1,002,115 = 1,002,115
and
-1 x -1,002,115 = 1,002,115
Notice both answers equal 1,002,115
With that explanation out of the way, let's continue. Next, we take the number 1,002,115 and divide it by 2:
1,002,115 ÷ 2 = 501,057.5
If the quotient is a whole number, then 2 and 501,057.5 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 | 1,002,115 | |
| -1 | -1,002,115 |
Now, we try dividing 1,002,115 by 3:
1,002,115 ÷ 3 = 334,038.3333
If the quotient is a whole number, then 3 and 334,038.3333 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 | 1,002,115 | |
| -1 | -1,002,115 |
Let's try dividing by 4:
1,002,115 ÷ 4 = 250,528.75
If the quotient is a whole number, then 4 and 250,528.75 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 | 1,002,115 | |
| -1 | 1,002,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 59 | 79 | 215 | 295 | 395 | 2,537 | 3,397 | 4,661 | 12,685 | 16,985 | 23,305 | 200,423 | 1,002,115 |
| -1 | -5 | -43 | -59 | -79 | -215 | -295 | -395 | -2,537 | -3,397 | -4,661 | -12,685 | -16,985 | -23,305 | -200,423 | -1,002,115 |
