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 471,610,843, 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 | 471,610,843 | |
| -1 | -471,610,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 471,610,843.
Example:
1 x 471,610,843 = 471,610,843
and
-1 x -471,610,843 = 471,610,843
Notice both answers equal 471,610,843
With that explanation out of the way, let's continue. Next, we take the number 471,610,843 and divide it by 2:
471,610,843 ÷ 2 = 235,805,421.5
If the quotient is a whole number, then 2 and 235,805,421.5 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 | 471,610,843 | |
| -1 | -471,610,843 |
Now, we try dividing 471,610,843 by 3:
471,610,843 ÷ 3 = 157,203,614.3333
If the quotient is a whole number, then 3 and 157,203,614.3333 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 | 471,610,843 | |
| -1 | -471,610,843 |
Let's try dividing by 4:
471,610,843 ÷ 4 = 117,902,710.75
If the quotient is a whole number, then 4 and 117,902,710.75 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 | 471,610,843 | |
| -1 | 471,610,843 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 37 | 341 | 407 | 1,147 | 12,617 | 37,379 | 411,169 | 1,158,749 | 1,383,023 | 12,746,239 | 15,213,253 | 42,873,713 | 471,610,843 |
| -1 | -11 | -31 | -37 | -341 | -407 | -1,147 | -12,617 | -37,379 | -411,169 | -1,158,749 | -1,383,023 | -12,746,239 | -15,213,253 | -42,873,713 | -471,610,843 |
