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 244,407,515, 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 | 244,407,515 | |
| -1 | -244,407,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,407,515.
Example:
1 x 244,407,515 = 244,407,515
and
-1 x -244,407,515 = 244,407,515
Notice both answers equal 244,407,515
With that explanation out of the way, let's continue. Next, we take the number 244,407,515 and divide it by 2:
244,407,515 ÷ 2 = 122,203,757.5
If the quotient is a whole number, then 2 and 122,203,757.5 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 | 244,407,515 | |
| -1 | -244,407,515 |
Now, we try dividing 244,407,515 by 3:
244,407,515 ÷ 3 = 81,469,171.6667
If the quotient is a whole number, then 3 and 81,469,171.6667 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 | 244,407,515 | |
| -1 | -244,407,515 |
Let's try dividing by 4:
244,407,515 ÷ 4 = 61,101,878.75
If the quotient is a whole number, then 4 and 61,101,878.75 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 | 244,407,515 | |
| -1 | 244,407,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 643 | 3,215 | 6,911 | 7,073 | 34,555 | 35,365 | 76,021 | 380,105 | 4,443,773 | 22,218,865 | 48,881,503 | 244,407,515 |
| -1 | -5 | -11 | -55 | -643 | -3,215 | -6,911 | -7,073 | -34,555 | -35,365 | -76,021 | -380,105 | -4,443,773 | -22,218,865 | -48,881,503 | -244,407,515 |
