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 11,503,565, 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 | 11,503,565 | |
| -1 | -11,503,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,503,565.
Example:
1 x 11,503,565 = 11,503,565
and
-1 x -11,503,565 = 11,503,565
Notice both answers equal 11,503,565
With that explanation out of the way, let's continue. Next, we take the number 11,503,565 and divide it by 2:
11,503,565 ÷ 2 = 5,751,782.5
If the quotient is a whole number, then 2 and 5,751,782.5 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 | 11,503,565 | |
| -1 | -11,503,565 |
Now, we try dividing 11,503,565 by 3:
11,503,565 ÷ 3 = 3,834,521.6667
If the quotient is a whole number, then 3 and 3,834,521.6667 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 | 11,503,565 | |
| -1 | -11,503,565 |
Let's try dividing by 4:
11,503,565 ÷ 4 = 2,875,891.25
If the quotient is a whole number, then 4 and 2,875,891.25 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 | 11,503,565 | |
| -1 | 11,503,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 67 | 115 | 335 | 1,493 | 1,541 | 7,465 | 7,705 | 34,339 | 100,031 | 171,695 | 500,155 | 2,300,713 | 11,503,565 |
| -1 | -5 | -23 | -67 | -115 | -335 | -1,493 | -1,541 | -7,465 | -7,705 | -34,339 | -100,031 | -171,695 | -500,155 | -2,300,713 | -11,503,565 |
