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 774,553,673, 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 | 774,553,673 | |
| -1 | -774,553,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 774,553,673.
Example:
1 x 774,553,673 = 774,553,673
and
-1 x -774,553,673 = 774,553,673
Notice both answers equal 774,553,673
With that explanation out of the way, let's continue. Next, we take the number 774,553,673 and divide it by 2:
774,553,673 ÷ 2 = 387,276,836.5
If the quotient is a whole number, then 2 and 387,276,836.5 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 | 774,553,673 | |
| -1 | -774,553,673 |
Now, we try dividing 774,553,673 by 3:
774,553,673 ÷ 3 = 258,184,557.6667
If the quotient is a whole number, then 3 and 258,184,557.6667 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 | 774,553,673 | |
| -1 | -774,553,673 |
Let's try dividing by 4:
774,553,673 ÷ 4 = 193,638,418.25
If the quotient is a whole number, then 4 and 193,638,418.25 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 | 774,553,673 | |
| -1 | 774,553,673 |
If you did it right, you will end up with this table:
| 1 | 41 | 109 | 263 | 659 | 4,469 | 10,783 | 27,019 | 28,667 | 71,831 | 173,317 | 1,175,347 | 2,945,071 | 7,105,997 | 18,891,553 | 774,553,673 |
| -1 | -41 | -109 | -263 | -659 | -4,469 | -10,783 | -27,019 | -28,667 | -71,831 | -173,317 | -1,175,347 | -2,945,071 | -7,105,997 | -18,891,553 | -774,553,673 |
