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 6,446,225, 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 | 6,446,225 | |
| -1 | -6,446,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,446,225.
Example:
1 x 6,446,225 = 6,446,225
and
-1 x -6,446,225 = 6,446,225
Notice both answers equal 6,446,225
With that explanation out of the way, let's continue. Next, we take the number 6,446,225 and divide it by 2:
6,446,225 ÷ 2 = 3,223,112.5
If the quotient is a whole number, then 2 and 3,223,112.5 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 | 6,446,225 | |
| -1 | -6,446,225 |
Now, we try dividing 6,446,225 by 3:
6,446,225 ÷ 3 = 2,148,741.6667
If the quotient is a whole number, then 3 and 2,148,741.6667 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 | 6,446,225 | |
| -1 | -6,446,225 |
Let's try dividing by 4:
6,446,225 ÷ 4 = 1,611,556.25
If the quotient is a whole number, then 4 and 1,611,556.25 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 | 6,446,225 | |
| -1 | 6,446,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 41 | 95 | 205 | 331 | 475 | 779 | 1,025 | 1,655 | 3,895 | 6,289 | 8,275 | 13,571 | 19,475 | 31,445 | 67,855 | 157,225 | 257,849 | 339,275 | 1,289,245 | 6,446,225 |
| -1 | -5 | -19 | -25 | -41 | -95 | -205 | -331 | -475 | -779 | -1,025 | -1,655 | -3,895 | -6,289 | -8,275 | -13,571 | -19,475 | -31,445 | -67,855 | -157,225 | -257,849 | -339,275 | -1,289,245 | -6,446,225 |
