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 42,627,065, 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 | 42,627,065 | |
| -1 | -42,627,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,627,065.
Example:
1 x 42,627,065 = 42,627,065
and
-1 x -42,627,065 = 42,627,065
Notice both answers equal 42,627,065
With that explanation out of the way, let's continue. Next, we take the number 42,627,065 and divide it by 2:
42,627,065 ÷ 2 = 21,313,532.5
If the quotient is a whole number, then 2 and 21,313,532.5 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 | 42,627,065 | |
| -1 | -42,627,065 |
Now, we try dividing 42,627,065 by 3:
42,627,065 ÷ 3 = 14,209,021.6667
If the quotient is a whole number, then 3 and 14,209,021.6667 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 | 42,627,065 | |
| -1 | -42,627,065 |
Let's try dividing by 4:
42,627,065 ÷ 4 = 10,656,766.25
If the quotient is a whole number, then 4 and 10,656,766.25 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 | 42,627,065 | |
| -1 | 42,627,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 103 | 515 | 1,339 | 6,367 | 6,695 | 31,835 | 82,771 | 413,855 | 655,801 | 3,279,005 | 8,525,413 | 42,627,065 |
| -1 | -5 | -13 | -65 | -103 | -515 | -1,339 | -6,367 | -6,695 | -31,835 | -82,771 | -413,855 | -655,801 | -3,279,005 | -8,525,413 | -42,627,065 |
