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 723,124,255, 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 | 723,124,255 | |
| -1 | -723,124,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 723,124,255.
Example:
1 x 723,124,255 = 723,124,255
and
-1 x -723,124,255 = 723,124,255
Notice both answers equal 723,124,255
With that explanation out of the way, let's continue. Next, we take the number 723,124,255 and divide it by 2:
723,124,255 ÷ 2 = 361,562,127.5
If the quotient is a whole number, then 2 and 361,562,127.5 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 | 723,124,255 | |
| -1 | -723,124,255 |
Now, we try dividing 723,124,255 by 3:
723,124,255 ÷ 3 = 241,041,418.3333
If the quotient is a whole number, then 3 and 241,041,418.3333 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 | 723,124,255 | |
| -1 | -723,124,255 |
Let's try dividing by 4:
723,124,255 ÷ 4 = 180,781,063.75
If the quotient is a whole number, then 4 and 180,781,063.75 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 | 723,124,255 | |
| -1 | 723,124,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 898,291 | 4,491,455 | 6,288,037 | 20,660,693 | 31,440,185 | 103,303,465 | 144,624,851 | 723,124,255 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -898,291 | -4,491,455 | -6,288,037 | -20,660,693 | -31,440,185 | -103,303,465 | -144,624,851 | -723,124,255 |
