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 422,655,155, 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 | 422,655,155 | |
| -1 | -422,655,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 422,655,155.
Example:
1 x 422,655,155 = 422,655,155
and
-1 x -422,655,155 = 422,655,155
Notice both answers equal 422,655,155
With that explanation out of the way, let's continue. Next, we take the number 422,655,155 and divide it by 2:
422,655,155 ÷ 2 = 211,327,577.5
If the quotient is a whole number, then 2 and 211,327,577.5 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 | 422,655,155 | |
| -1 | -422,655,155 |
Now, we try dividing 422,655,155 by 3:
422,655,155 ÷ 3 = 140,885,051.6667
If the quotient is a whole number, then 3 and 140,885,051.6667 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 | 422,655,155 | |
| -1 | -422,655,155 |
Let's try dividing by 4:
422,655,155 ÷ 4 = 105,663,788.75
If the quotient is a whole number, then 4 and 105,663,788.75 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 | 422,655,155 | |
| -1 | 422,655,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 211 | 1,055 | 2,743 | 13,715 | 30,817 | 154,085 | 400,621 | 2,003,105 | 6,502,387 | 32,511,935 | 84,531,031 | 422,655,155 |
| -1 | -5 | -13 | -65 | -211 | -1,055 | -2,743 | -13,715 | -30,817 | -154,085 | -400,621 | -2,003,105 | -6,502,387 | -32,511,935 | -84,531,031 | -422,655,155 |
