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 244,351,355, 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 | 244,351,355 | |
| -1 | -244,351,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,351,355.
Example:
1 x 244,351,355 = 244,351,355
and
-1 x -244,351,355 = 244,351,355
Notice both answers equal 244,351,355
With that explanation out of the way, let's continue. Next, we take the number 244,351,355 and divide it by 2:
244,351,355 ÷ 2 = 122,175,677.5
If the quotient is a whole number, then 2 and 122,175,677.5 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 | 244,351,355 | |
| -1 | -244,351,355 |
Now, we try dividing 244,351,355 by 3:
244,351,355 ÷ 3 = 81,450,451.6667
If the quotient is a whole number, then 3 and 81,450,451.6667 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 | 244,351,355 | |
| -1 | -244,351,355 |
Let's try dividing by 4:
244,351,355 ÷ 4 = 61,087,838.75
If the quotient is a whole number, then 4 and 61,087,838.75 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 | 244,351,355 | |
| -1 | 244,351,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 401 | 2,005 | 2,593 | 12,965 | 18,847 | 94,235 | 121,871 | 609,355 | 1,039,793 | 5,198,965 | 48,870,271 | 244,351,355 |
| -1 | -5 | -47 | -235 | -401 | -2,005 | -2,593 | -12,965 | -18,847 | -94,235 | -121,871 | -609,355 | -1,039,793 | -5,198,965 | -48,870,271 | -244,351,355 |
