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 5,107,265, 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 | 5,107,265 | |
| -1 | -5,107,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,107,265.
Example:
1 x 5,107,265 = 5,107,265
and
-1 x -5,107,265 = 5,107,265
Notice both answers equal 5,107,265
With that explanation out of the way, let's continue. Next, we take the number 5,107,265 and divide it by 2:
5,107,265 ÷ 2 = 2,553,632.5
If the quotient is a whole number, then 2 and 2,553,632.5 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 | 5,107,265 | |
| -1 | -5,107,265 |
Now, we try dividing 5,107,265 by 3:
5,107,265 ÷ 3 = 1,702,421.6667
If the quotient is a whole number, then 3 and 1,702,421.6667 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 | 5,107,265 | |
| -1 | -5,107,265 |
Let's try dividing by 4:
5,107,265 ÷ 4 = 1,276,816.25
If the quotient is a whole number, then 4 and 1,276,816.25 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 | 5,107,265 | |
| -1 | 5,107,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 89 | 115 | 445 | 499 | 2,047 | 2,495 | 10,235 | 11,477 | 44,411 | 57,385 | 222,055 | 1,021,453 | 5,107,265 |
| -1 | -5 | -23 | -89 | -115 | -445 | -499 | -2,047 | -2,495 | -10,235 | -11,477 | -44,411 | -57,385 | -222,055 | -1,021,453 | -5,107,265 |
