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 1,030,285, 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 | 1,030,285 | |
| -1 | -1,030,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,030,285.
Example:
1 x 1,030,285 = 1,030,285
and
-1 x -1,030,285 = 1,030,285
Notice both answers equal 1,030,285
With that explanation out of the way, let's continue. Next, we take the number 1,030,285 and divide it by 2:
1,030,285 ÷ 2 = 515,142.5
If the quotient is a whole number, then 2 and 515,142.5 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 | 1,030,285 | |
| -1 | -1,030,285 |
Now, we try dividing 1,030,285 by 3:
1,030,285 ÷ 3 = 343,428.3333
If the quotient is a whole number, then 3 and 343,428.3333 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 | 1,030,285 | |
| -1 | -1,030,285 |
Let's try dividing by 4:
1,030,285 ÷ 4 = 257,571.25
If the quotient is a whole number, then 4 and 257,571.25 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 | 1,030,285 | |
| -1 | 1,030,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 31 | 85 | 115 | 155 | 289 | 391 | 527 | 713 | 1,445 | 1,955 | 2,635 | 3,565 | 6,647 | 8,959 | 12,121 | 33,235 | 44,795 | 60,605 | 206,057 | 1,030,285 |
| -1 | -5 | -17 | -23 | -31 | -85 | -115 | -155 | -289 | -391 | -527 | -713 | -1,445 | -1,955 | -2,635 | -3,565 | -6,647 | -8,959 | -12,121 | -33,235 | -44,795 | -60,605 | -206,057 | -1,030,285 |
