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 13,650,505, 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 | 13,650,505 | |
| -1 | -13,650,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,650,505.
Example:
1 x 13,650,505 = 13,650,505
and
-1 x -13,650,505 = 13,650,505
Notice both answers equal 13,650,505
With that explanation out of the way, let's continue. Next, we take the number 13,650,505 and divide it by 2:
13,650,505 ÷ 2 = 6,825,252.5
If the quotient is a whole number, then 2 and 6,825,252.5 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 | 13,650,505 | |
| -1 | -13,650,505 |
Now, we try dividing 13,650,505 by 3:
13,650,505 ÷ 3 = 4,550,168.3333
If the quotient is a whole number, then 3 and 4,550,168.3333 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 | 13,650,505 | |
| -1 | -13,650,505 |
Let's try dividing by 4:
13,650,505 ÷ 4 = 3,412,626.25
If the quotient is a whole number, then 4 and 3,412,626.25 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 | 13,650,505 | |
| -1 | 13,650,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 283 | 877 | 1,415 | 3,113 | 4,385 | 9,647 | 15,565 | 48,235 | 248,191 | 1,240,955 | 2,730,101 | 13,650,505 |
| -1 | -5 | -11 | -55 | -283 | -877 | -1,415 | -3,113 | -4,385 | -9,647 | -15,565 | -48,235 | -248,191 | -1,240,955 | -2,730,101 | -13,650,505 |
