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 5,318,651, 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 | 5,318,651 | |
| -1 | -5,318,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,318,651.
Example:
1 x 5,318,651 = 5,318,651
and
-1 x -5,318,651 = 5,318,651
Notice both answers equal 5,318,651
With that explanation out of the way, let's continue. Next, we take the number 5,318,651 and divide it by 2:
5,318,651 ÷ 2 = 2,659,325.5
If the quotient is a whole number, then 2 and 2,659,325.5 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 | 5,318,651 | |
| -1 | -5,318,651 |
Now, we try dividing 5,318,651 by 3:
5,318,651 ÷ 3 = 1,772,883.6667
If the quotient is a whole number, then 3 and 1,772,883.6667 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 | 5,318,651 | |
| -1 | -5,318,651 |
Let's try dividing by 4:
5,318,651 ÷ 4 = 1,329,662.75
If the quotient is a whole number, then 4 and 1,329,662.75 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 | 5,318,651 | |
| -1 | 5,318,651 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 61 | 247 | 353 | 793 | 1,159 | 4,589 | 6,707 | 15,067 | 21,533 | 87,191 | 279,929 | 409,127 | 5,318,651 |
| -1 | -13 | -19 | -61 | -247 | -353 | -793 | -1,159 | -4,589 | -6,707 | -15,067 | -21,533 | -87,191 | -279,929 | -409,127 | -5,318,651 |
