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 722,241,443, 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 | 722,241,443 | |
| -1 | -722,241,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 722,241,443.
Example:
1 x 722,241,443 = 722,241,443
and
-1 x -722,241,443 = 722,241,443
Notice both answers equal 722,241,443
With that explanation out of the way, let's continue. Next, we take the number 722,241,443 and divide it by 2:
722,241,443 ÷ 2 = 361,120,721.5
If the quotient is a whole number, then 2 and 361,120,721.5 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 | 722,241,443 | |
| -1 | -722,241,443 |
Now, we try dividing 722,241,443 by 3:
722,241,443 ÷ 3 = 240,747,147.6667
If the quotient is a whole number, then 3 and 240,747,147.6667 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 | 722,241,443 | |
| -1 | -722,241,443 |
Let's try dividing by 4:
722,241,443 ÷ 4 = 180,560,360.75
If the quotient is a whole number, then 4 and 180,560,360.75 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 | 722,241,443 | |
| -1 | 722,241,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 2,849 | 253,507 | 1,774,549 | 2,788,577 | 9,379,759 | 19,520,039 | 65,658,313 | 103,177,349 | 722,241,443 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -2,849 | -253,507 | -1,774,549 | -2,788,577 | -9,379,759 | -19,520,039 | -65,658,313 | -103,177,349 | -722,241,443 |
