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 440,603,215, 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 | 440,603,215 | |
| -1 | -440,603,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,603,215.
Example:
1 x 440,603,215 = 440,603,215
and
-1 x -440,603,215 = 440,603,215
Notice both answers equal 440,603,215
With that explanation out of the way, let's continue. Next, we take the number 440,603,215 and divide it by 2:
440,603,215 ÷ 2 = 220,301,607.5
If the quotient is a whole number, then 2 and 220,301,607.5 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 | 440,603,215 | |
| -1 | -440,603,215 |
Now, we try dividing 440,603,215 by 3:
440,603,215 ÷ 3 = 146,867,738.3333
If the quotient is a whole number, then 3 and 146,867,738.3333 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 | 440,603,215 | |
| -1 | -440,603,215 |
Let's try dividing by 4:
440,603,215 ÷ 4 = 110,150,803.75
If the quotient is a whole number, then 4 and 110,150,803.75 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 | 440,603,215 | |
| -1 | 440,603,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 183,203 | 916,015 | 2,381,639 | 6,778,511 | 11,908,195 | 33,892,555 | 88,120,643 | 440,603,215 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -183,203 | -916,015 | -2,381,639 | -6,778,511 | -11,908,195 | -33,892,555 | -88,120,643 | -440,603,215 |
