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 42,502,055, 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 | 42,502,055 | |
| -1 | -42,502,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,502,055.
Example:
1 x 42,502,055 = 42,502,055
and
-1 x -42,502,055 = 42,502,055
Notice both answers equal 42,502,055
With that explanation out of the way, let's continue. Next, we take the number 42,502,055 and divide it by 2:
42,502,055 ÷ 2 = 21,251,027.5
If the quotient is a whole number, then 2 and 21,251,027.5 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 | 42,502,055 | |
| -1 | -42,502,055 |
Now, we try dividing 42,502,055 by 3:
42,502,055 ÷ 3 = 14,167,351.6667
If the quotient is a whole number, then 3 and 14,167,351.6667 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 | 42,502,055 | |
| -1 | -42,502,055 |
Let's try dividing by 4:
42,502,055 ÷ 4 = 10,625,513.75
If the quotient is a whole number, then 4 and 10,625,513.75 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 | 42,502,055 | |
| -1 | 42,502,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 305 | 331 | 421 | 1,655 | 2,105 | 20,191 | 25,681 | 100,955 | 128,405 | 139,351 | 696,755 | 8,500,411 | 42,502,055 |
| -1 | -5 | -61 | -305 | -331 | -421 | -1,655 | -2,105 | -20,191 | -25,681 | -100,955 | -128,405 | -139,351 | -696,755 | -8,500,411 | -42,502,055 |
