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 422,412,325, 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 | 422,412,325 | |
| -1 | -422,412,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 422,412,325.
Example:
1 x 422,412,325 = 422,412,325
and
-1 x -422,412,325 = 422,412,325
Notice both answers equal 422,412,325
With that explanation out of the way, let's continue. Next, we take the number 422,412,325 and divide it by 2:
422,412,325 ÷ 2 = 211,206,162.5
If the quotient is a whole number, then 2 and 211,206,162.5 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 | 422,412,325 | |
| -1 | -422,412,325 |
Now, we try dividing 422,412,325 by 3:
422,412,325 ÷ 3 = 140,804,108.3333
If the quotient is a whole number, then 3 and 140,804,108.3333 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 | 422,412,325 | |
| -1 | -422,412,325 |
Let's try dividing by 4:
422,412,325 ÷ 4 = 105,603,081.25
If the quotient is a whole number, then 4 and 105,603,081.25 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 | 422,412,325 | |
| -1 | 422,412,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 197 | 199 | 431 | 985 | 995 | 2,155 | 4,925 | 4,975 | 10,775 | 39,203 | 84,907 | 85,769 | 196,015 | 424,535 | 428,845 | 980,075 | 2,122,675 | 2,144,225 | 16,896,493 | 84,482,465 | 422,412,325 |
| -1 | -5 | -25 | -197 | -199 | -431 | -985 | -995 | -2,155 | -4,925 | -4,975 | -10,775 | -39,203 | -84,907 | -85,769 | -196,015 | -424,535 | -428,845 | -980,075 | -2,122,675 | -2,144,225 | -16,896,493 | -84,482,465 | -422,412,325 |
