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 5,125,315, 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 | 5,125,315 | |
| -1 | -5,125,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,125,315.
Example:
1 x 5,125,315 = 5,125,315
and
-1 x -5,125,315 = 5,125,315
Notice both answers equal 5,125,315
With that explanation out of the way, let's continue. Next, we take the number 5,125,315 and divide it by 2:
5,125,315 ÷ 2 = 2,562,657.5
If the quotient is a whole number, then 2 and 2,562,657.5 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 | 5,125,315 | |
| -1 | -5,125,315 |
Now, we try dividing 5,125,315 by 3:
5,125,315 ÷ 3 = 1,708,438.3333
If the quotient is a whole number, then 3 and 1,708,438.3333 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 | 5,125,315 | |
| -1 | -5,125,315 |
Let's try dividing by 4:
5,125,315 ÷ 4 = 1,281,328.75
If the quotient is a whole number, then 4 and 1,281,328.75 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 | 5,125,315 | |
| -1 | 5,125,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 377 | 1,885 | 2,719 | 13,595 | 35,347 | 78,851 | 176,735 | 394,255 | 1,025,063 | 5,125,315 |
| -1 | -5 | -13 | -29 | -65 | -145 | -377 | -1,885 | -2,719 | -13,595 | -35,347 | -78,851 | -176,735 | -394,255 | -1,025,063 | -5,125,315 |
