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 6,442,699, 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 | 6,442,699 | |
| -1 | -6,442,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,442,699.
Example:
1 x 6,442,699 = 6,442,699
and
-1 x -6,442,699 = 6,442,699
Notice both answers equal 6,442,699
With that explanation out of the way, let's continue. Next, we take the number 6,442,699 and divide it by 2:
6,442,699 ÷ 2 = 3,221,349.5
If the quotient is a whole number, then 2 and 3,221,349.5 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 | 6,442,699 | |
| -1 | -6,442,699 |
Now, we try dividing 6,442,699 by 3:
6,442,699 ÷ 3 = 2,147,566.3333
If the quotient is a whole number, then 3 and 2,147,566.3333 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 | 6,442,699 | |
| -1 | -6,442,699 |
Let's try dividing by 4:
6,442,699 ÷ 4 = 1,610,674.75
If the quotient is a whole number, then 4 and 1,610,674.75 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 | 6,442,699 | |
| -1 | 6,442,699 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 41 | 137 | 1,147 | 1,271 | 1,517 | 4,247 | 5,069 | 5,617 | 47,027 | 157,139 | 174,127 | 207,829 | 6,442,699 |
| -1 | -31 | -37 | -41 | -137 | -1,147 | -1,271 | -1,517 | -4,247 | -5,069 | -5,617 | -47,027 | -157,139 | -174,127 | -207,829 | -6,442,699 |
