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 13,650,565, 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 | 13,650,565 | |
| -1 | -13,650,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,650,565.
Example:
1 x 13,650,565 = 13,650,565
and
-1 x -13,650,565 = 13,650,565
Notice both answers equal 13,650,565
With that explanation out of the way, let's continue. Next, we take the number 13,650,565 and divide it by 2:
13,650,565 ÷ 2 = 6,825,282.5
If the quotient is a whole number, then 2 and 6,825,282.5 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 | 13,650,565 | |
| -1 | -13,650,565 |
Now, we try dividing 13,650,565 by 3:
13,650,565 ÷ 3 = 4,550,188.3333
If the quotient is a whole number, then 3 and 4,550,188.3333 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 | 13,650,565 | |
| -1 | -13,650,565 |
Let's try dividing by 4:
13,650,565 ÷ 4 = 3,412,641.25
If the quotient is a whole number, then 4 and 3,412,641.25 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 | 13,650,565 | |
| -1 | 13,650,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 173 | 215 | 367 | 865 | 1,835 | 7,439 | 15,781 | 37,195 | 63,491 | 78,905 | 317,455 | 2,730,113 | 13,650,565 |
| -1 | -5 | -43 | -173 | -215 | -367 | -865 | -1,835 | -7,439 | -15,781 | -37,195 | -63,491 | -78,905 | -317,455 | -2,730,113 | -13,650,565 |
