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 244,243,415, 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 | 244,243,415 | |
| -1 | -244,243,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,243,415.
Example:
1 x 244,243,415 = 244,243,415
and
-1 x -244,243,415 = 244,243,415
Notice both answers equal 244,243,415
With that explanation out of the way, let's continue. Next, we take the number 244,243,415 and divide it by 2:
244,243,415 ÷ 2 = 122,121,707.5
If the quotient is a whole number, then 2 and 122,121,707.5 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 | 244,243,415 | |
| -1 | -244,243,415 |
Now, we try dividing 244,243,415 by 3:
244,243,415 ÷ 3 = 81,414,471.6667
If the quotient is a whole number, then 3 and 81,414,471.6667 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 | 244,243,415 | |
| -1 | -244,243,415 |
Let's try dividing by 4:
244,243,415 ÷ 4 = 61,060,853.75
If the quotient is a whole number, then 4 and 61,060,853.75 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 | 244,243,415 | |
| -1 | 244,243,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 233 | 1,165 | 3,029 | 15,145 | 16,127 | 80,635 | 209,651 | 1,048,255 | 3,757,591 | 18,787,955 | 48,848,683 | 244,243,415 |
| -1 | -5 | -13 | -65 | -233 | -1,165 | -3,029 | -15,145 | -16,127 | -80,635 | -209,651 | -1,048,255 | -3,757,591 | -18,787,955 | -48,848,683 | -244,243,415 |
