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 5,188,001, 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 | 5,188,001 | |
| -1 | -5,188,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,188,001.
Example:
1 x 5,188,001 = 5,188,001
and
-1 x -5,188,001 = 5,188,001
Notice both answers equal 5,188,001
With that explanation out of the way, let's continue. Next, we take the number 5,188,001 and divide it by 2:
5,188,001 ÷ 2 = 2,594,000.5
If the quotient is a whole number, then 2 and 2,594,000.5 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 | 5,188,001 | |
| -1 | -5,188,001 |
Now, we try dividing 5,188,001 by 3:
5,188,001 ÷ 3 = 1,729,333.6667
If the quotient is a whole number, then 3 and 1,729,333.6667 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 | 5,188,001 | |
| -1 | -5,188,001 |
Let's try dividing by 4:
5,188,001 ÷ 4 = 1,297,000.25
If the quotient is a whole number, then 4 and 1,297,000.25 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 | 5,188,001 | |
| -1 | 5,188,001 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 91 | 329 | 611 | 1,213 | 4,277 | 8,491 | 15,769 | 57,011 | 110,383 | 399,077 | 741,143 | 5,188,001 |
| -1 | -7 | -13 | -47 | -91 | -329 | -611 | -1,213 | -4,277 | -8,491 | -15,769 | -57,011 | -110,383 | -399,077 | -741,143 | -5,188,001 |
