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 633,845,471, 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 | 633,845,471 | |
| -1 | -633,845,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 633,845,471.
Example:
1 x 633,845,471 = 633,845,471
and
-1 x -633,845,471 = 633,845,471
Notice both answers equal 633,845,471
With that explanation out of the way, let's continue. Next, we take the number 633,845,471 and divide it by 2:
633,845,471 ÷ 2 = 316,922,735.5
If the quotient is a whole number, then 2 and 316,922,735.5 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 | 633,845,471 | |
| -1 | -633,845,471 |
Now, we try dividing 633,845,471 by 3:
633,845,471 ÷ 3 = 211,281,823.6667
If the quotient is a whole number, then 3 and 211,281,823.6667 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 | 633,845,471 | |
| -1 | -633,845,471 |
Let's try dividing by 4:
633,845,471 ÷ 4 = 158,461,367.75
If the quotient is a whole number, then 4 and 158,461,367.75 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 | 633,845,471 | |
| -1 | 633,845,471 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 331 | 497 | 2,317 | 3,853 | 23,501 | 26,971 | 164,507 | 273,563 | 1,275,343 | 1,914,941 | 8,927,401 | 90,549,353 | 633,845,471 |
| -1 | -7 | -71 | -331 | -497 | -2,317 | -3,853 | -23,501 | -26,971 | -164,507 | -273,563 | -1,275,343 | -1,914,941 | -8,927,401 | -90,549,353 | -633,845,471 |
