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 422,113,105, 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 | 422,113,105 | |
| -1 | -422,113,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 422,113,105.
Example:
1 x 422,113,105 = 422,113,105
and
-1 x -422,113,105 = 422,113,105
Notice both answers equal 422,113,105
With that explanation out of the way, let's continue. Next, we take the number 422,113,105 and divide it by 2:
422,113,105 ÷ 2 = 211,056,552.5
If the quotient is a whole number, then 2 and 211,056,552.5 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 | 422,113,105 | |
| -1 | -422,113,105 |
Now, we try dividing 422,113,105 by 3:
422,113,105 ÷ 3 = 140,704,368.3333
If the quotient is a whole number, then 3 and 140,704,368.3333 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 | 422,113,105 | |
| -1 | -422,113,105 |
Let's try dividing by 4:
422,113,105 ÷ 4 = 105,528,276.25
If the quotient is a whole number, then 4 and 105,528,276.25 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 | 422,113,105 | |
| -1 | 422,113,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 355 | 739 | 1,609 | 3,695 | 8,045 | 52,469 | 114,239 | 262,345 | 571,195 | 1,189,051 | 5,945,255 | 84,422,621 | 422,113,105 |
| -1 | -5 | -71 | -355 | -739 | -1,609 | -3,695 | -8,045 | -52,469 | -114,239 | -262,345 | -571,195 | -1,189,051 | -5,945,255 | -84,422,621 | -422,113,105 |
