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 5,207,875, 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 | 5,207,875 | |
| -1 | -5,207,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,207,875.
Example:
1 x 5,207,875 = 5,207,875
and
-1 x -5,207,875 = 5,207,875
Notice both answers equal 5,207,875
With that explanation out of the way, let's continue. Next, we take the number 5,207,875 and divide it by 2:
5,207,875 ÷ 2 = 2,603,937.5
If the quotient is a whole number, then 2 and 2,603,937.5 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 | 5,207,875 | |
| -1 | -5,207,875 |
Now, we try dividing 5,207,875 by 3:
5,207,875 ÷ 3 = 1,735,958.3333
If the quotient is a whole number, then 3 and 1,735,958.3333 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 | 5,207,875 | |
| -1 | -5,207,875 |
Let's try dividing by 4:
5,207,875 ÷ 4 = 1,301,968.75
If the quotient is a whole number, then 4 and 1,301,968.75 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 | 5,207,875 | |
| -1 | 5,207,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 125 | 305 | 683 | 1,525 | 3,415 | 7,625 | 17,075 | 41,663 | 85,375 | 208,315 | 1,041,575 | 5,207,875 |
| -1 | -5 | -25 | -61 | -125 | -305 | -683 | -1,525 | -3,415 | -7,625 | -17,075 | -41,663 | -85,375 | -208,315 | -1,041,575 | -5,207,875 |
