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 244,420,015, 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 | 244,420,015 | |
| -1 | -244,420,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,420,015.
Example:
1 x 244,420,015 = 244,420,015
and
-1 x -244,420,015 = 244,420,015
Notice both answers equal 244,420,015
With that explanation out of the way, let's continue. Next, we take the number 244,420,015 and divide it by 2:
244,420,015 ÷ 2 = 122,210,007.5
If the quotient is a whole number, then 2 and 122,210,007.5 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 | 244,420,015 | |
| -1 | -244,420,015 |
Now, we try dividing 244,420,015 by 3:
244,420,015 ÷ 3 = 81,473,338.3333
If the quotient is a whole number, then 3 and 81,473,338.3333 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 | 244,420,015 | |
| -1 | -244,420,015 |
Let's try dividing by 4:
244,420,015 ÷ 4 = 61,105,003.75
If the quotient is a whole number, then 4 and 61,105,003.75 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 | 244,420,015 | |
| -1 | 244,420,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 463 | 2,315 | 3,241 | 15,083 | 16,205 | 75,415 | 105,581 | 527,905 | 6,983,429 | 34,917,145 | 48,884,003 | 244,420,015 |
| -1 | -5 | -7 | -35 | -463 | -2,315 | -3,241 | -15,083 | -16,205 | -75,415 | -105,581 | -527,905 | -6,983,429 | -34,917,145 | -48,884,003 | -244,420,015 |
