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 655,426,471, 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 | 655,426,471 | |
| -1 | -655,426,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 655,426,471.
Example:
1 x 655,426,471 = 655,426,471
and
-1 x -655,426,471 = 655,426,471
Notice both answers equal 655,426,471
With that explanation out of the way, let's continue. Next, we take the number 655,426,471 and divide it by 2:
655,426,471 ÷ 2 = 327,713,235.5
If the quotient is a whole number, then 2 and 327,713,235.5 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 | 655,426,471 | |
| -1 | -655,426,471 |
Now, we try dividing 655,426,471 by 3:
655,426,471 ÷ 3 = 218,475,490.3333
If the quotient is a whole number, then 3 and 218,475,490.3333 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 | 655,426,471 | |
| -1 | -655,426,471 |
Let's try dividing by 4:
655,426,471 ÷ 4 = 163,856,617.75
If the quotient is a whole number, then 4 and 163,856,617.75 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 | 655,426,471 | |
| -1 | 655,426,471 |
If you did it right, you will end up with this table:
| 1 | 7 | 101 | 433 | 707 | 2,141 | 3,031 | 14,987 | 43,733 | 216,241 | 306,131 | 927,053 | 1,513,687 | 6,489,371 | 93,632,353 | 655,426,471 |
| -1 | -7 | -101 | -433 | -707 | -2,141 | -3,031 | -14,987 | -43,733 | -216,241 | -306,131 | -927,053 | -1,513,687 | -6,489,371 | -93,632,353 | -655,426,471 |
