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 1,300,535, 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 | 1,300,535 | |
| -1 | -1,300,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,300,535.
Example:
1 x 1,300,535 = 1,300,535
and
-1 x -1,300,535 = 1,300,535
Notice both answers equal 1,300,535
With that explanation out of the way, let's continue. Next, we take the number 1,300,535 and divide it by 2:
1,300,535 ÷ 2 = 650,267.5
If the quotient is a whole number, then 2 and 650,267.5 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 | 1,300,535 | |
| -1 | -1,300,535 |
Now, we try dividing 1,300,535 by 3:
1,300,535 ÷ 3 = 433,511.6667
If the quotient is a whole number, then 3 and 433,511.6667 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 | 1,300,535 | |
| -1 | -1,300,535 |
Let's try dividing by 4:
1,300,535 ÷ 4 = 325,133.75
If the quotient is a whole number, then 4 and 325,133.75 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 | 1,300,535 | |
| -1 | 1,300,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 263 | 989 | 1,315 | 4,945 | 6,049 | 11,309 | 30,245 | 56,545 | 260,107 | 1,300,535 |
| -1 | -5 | -23 | -43 | -115 | -215 | -263 | -989 | -1,315 | -4,945 | -6,049 | -11,309 | -30,245 | -56,545 | -260,107 | -1,300,535 |
