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 722,995, 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 | 722,995 | |
| -1 | -722,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 722,995.
Example:
1 x 722,995 = 722,995
and
-1 x -722,995 = 722,995
Notice both answers equal 722,995
With that explanation out of the way, let's continue. Next, we take the number 722,995 and divide it by 2:
722,995 ÷ 2 = 361,497.5
If the quotient is a whole number, then 2 and 361,497.5 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 | 722,995 | |
| -1 | -722,995 |
Now, we try dividing 722,995 by 3:
722,995 ÷ 3 = 240,998.3333
If the quotient is a whole number, then 3 and 240,998.3333 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 | 722,995 | |
| -1 | -722,995 |
Let's try dividing by 4:
722,995 ÷ 4 = 180,748.75
If the quotient is a whole number, then 4 and 180,748.75 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 | 722,995 | |
| -1 | 722,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 49 | 65 | 91 | 227 | 245 | 455 | 637 | 1,135 | 1,589 | 2,951 | 3,185 | 7,945 | 11,123 | 14,755 | 20,657 | 55,615 | 103,285 | 144,599 | 722,995 |
| -1 | -5 | -7 | -13 | -35 | -49 | -65 | -91 | -227 | -245 | -455 | -637 | -1,135 | -1,589 | -2,951 | -3,185 | -7,945 | -11,123 | -14,755 | -20,657 | -55,615 | -103,285 | -144,599 | -722,995 |
