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 5,266,807, 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 | 5,266,807 | |
| -1 | -5,266,807 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,266,807.
Example:
1 x 5,266,807 = 5,266,807
and
-1 x -5,266,807 = 5,266,807
Notice both answers equal 5,266,807
With that explanation out of the way, let's continue. Next, we take the number 5,266,807 and divide it by 2:
5,266,807 ÷ 2 = 2,633,403.5
If the quotient is a whole number, then 2 and 2,633,403.5 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 | 5,266,807 | |
| -1 | -5,266,807 |
Now, we try dividing 5,266,807 by 3:
5,266,807 ÷ 3 = 1,755,602.3333
If the quotient is a whole number, then 3 and 1,755,602.3333 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 | 5,266,807 | |
| -1 | -5,266,807 |
Let's try dividing by 4:
5,266,807 ÷ 4 = 1,316,701.75
If the quotient is a whole number, then 4 and 1,316,701.75 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 | 5,266,807 | |
| -1 | 5,266,807 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 1,867 | 2,821 | 13,069 | 24,271 | 57,877 | 169,897 | 405,139 | 752,401 | 5,266,807 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -1,867 | -2,821 | -13,069 | -24,271 | -57,877 | -169,897 | -405,139 | -752,401 | -5,266,807 |
