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 723,877, 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 | 723,877 | |
| -1 | -723,877 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 723,877.
Example:
1 x 723,877 = 723,877
and
-1 x -723,877 = 723,877
Notice both answers equal 723,877
With that explanation out of the way, let's continue. Next, we take the number 723,877 and divide it by 2:
723,877 ÷ 2 = 361,938.5
If the quotient is a whole number, then 2 and 361,938.5 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 | 723,877 | |
| -1 | -723,877 |
Now, we try dividing 723,877 by 3:
723,877 ÷ 3 = 241,292.3333
If the quotient is a whole number, then 3 and 241,292.3333 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 | 723,877 | |
| -1 | -723,877 |
Let's try dividing by 4:
723,877 ÷ 4 = 180,969.25
If the quotient is a whole number, then 4 and 180,969.25 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 | 723,877 | |
| -1 | 723,877 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 49 | 77 | 79 | 119 | 187 | 539 | 553 | 833 | 869 | 1,309 | 1,343 | 3,871 | 6,083 | 9,163 | 9,401 | 14,773 | 42,581 | 65,807 | 103,411 | 723,877 |
| -1 | -7 | -11 | -17 | -49 | -77 | -79 | -119 | -187 | -539 | -553 | -833 | -869 | -1,309 | -1,343 | -3,871 | -6,083 | -9,163 | -9,401 | -14,773 | -42,581 | -65,807 | -103,411 | -723,877 |
