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 722,411,845, 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 | 722,411,845 | |
| -1 | -722,411,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 722,411,845.
Example:
1 x 722,411,845 = 722,411,845
and
-1 x -722,411,845 = 722,411,845
Notice both answers equal 722,411,845
With that explanation out of the way, let's continue. Next, we take the number 722,411,845 and divide it by 2:
722,411,845 ÷ 2 = 361,205,922.5
If the quotient is a whole number, then 2 and 361,205,922.5 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 | 722,411,845 | |
| -1 | -722,411,845 |
Now, we try dividing 722,411,845 by 3:
722,411,845 ÷ 3 = 240,803,948.3333
If the quotient is a whole number, then 3 and 240,803,948.3333 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 | 722,411,845 | |
| -1 | -722,411,845 |
Let's try dividing by 4:
722,411,845 ÷ 4 = 180,602,961.25
If the quotient is a whole number, then 4 and 180,602,961.25 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 | 722,411,845 | |
| -1 | 722,411,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 223 | 277 | 1,115 | 1,385 | 2,339 | 11,695 | 61,771 | 308,855 | 521,597 | 647,903 | 2,607,985 | 3,239,515 | 144,482,369 | 722,411,845 |
| -1 | -5 | -223 | -277 | -1,115 | -1,385 | -2,339 | -11,695 | -61,771 | -308,855 | -521,597 | -647,903 | -2,607,985 | -3,239,515 | -144,482,369 | -722,411,845 |
