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 4,405,225, 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 | 4,405,225 | |
| -1 | -4,405,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,405,225.
Example:
1 x 4,405,225 = 4,405,225
and
-1 x -4,405,225 = 4,405,225
Notice both answers equal 4,405,225
With that explanation out of the way, let's continue. Next, we take the number 4,405,225 and divide it by 2:
4,405,225 ÷ 2 = 2,202,612.5
If the quotient is a whole number, then 2 and 2,202,612.5 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 | 4,405,225 | |
| -1 | -4,405,225 |
Now, we try dividing 4,405,225 by 3:
4,405,225 ÷ 3 = 1,468,408.3333
If the quotient is a whole number, then 3 and 1,468,408.3333 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 | 4,405,225 | |
| -1 | -4,405,225 |
Let's try dividing by 4:
4,405,225 ÷ 4 = 1,101,306.25
If the quotient is a whole number, then 4 and 1,101,306.25 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 | 4,405,225 | |
| -1 | 4,405,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 83 | 193 | 275 | 415 | 913 | 965 | 2,075 | 2,123 | 4,565 | 4,825 | 10,615 | 16,019 | 22,825 | 53,075 | 80,095 | 176,209 | 400,475 | 881,045 | 4,405,225 |
| -1 | -5 | -11 | -25 | -55 | -83 | -193 | -275 | -415 | -913 | -965 | -2,075 | -2,123 | -4,565 | -4,825 | -10,615 | -16,019 | -22,825 | -53,075 | -80,095 | -176,209 | -400,475 | -881,045 | -4,405,225 |
