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 1,205,303, 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 | 1,205,303 | |
| -1 | -1,205,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,205,303.
Example:
1 x 1,205,303 = 1,205,303
and
-1 x -1,205,303 = 1,205,303
Notice both answers equal 1,205,303
With that explanation out of the way, let's continue. Next, we take the number 1,205,303 and divide it by 2:
1,205,303 ÷ 2 = 602,651.5
If the quotient is a whole number, then 2 and 602,651.5 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 | 1,205,303 | |
| -1 | -1,205,303 |
Now, we try dividing 1,205,303 by 3:
1,205,303 ÷ 3 = 401,767.6667
If the quotient is a whole number, then 3 and 401,767.6667 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 | 1,205,303 | |
| -1 | -1,205,303 |
Let's try dividing by 4:
1,205,303 ÷ 4 = 301,325.75
If the quotient is a whole number, then 4 and 301,325.75 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 | 1,205,303 | |
| -1 | 1,205,303 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 73 | 79 | 209 | 803 | 869 | 1,387 | 1,501 | 5,767 | 15,257 | 16,511 | 63,437 | 109,573 | 1,205,303 |
| -1 | -11 | -19 | -73 | -79 | -209 | -803 | -869 | -1,387 | -1,501 | -5,767 | -15,257 | -16,511 | -63,437 | -109,573 | -1,205,303 |
