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 3,388,475, 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 | 3,388,475 | |
| -1 | -3,388,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,388,475.
Example:
1 x 3,388,475 = 3,388,475
and
-1 x -3,388,475 = 3,388,475
Notice both answers equal 3,388,475
With that explanation out of the way, let's continue. Next, we take the number 3,388,475 and divide it by 2:
3,388,475 ÷ 2 = 1,694,237.5
If the quotient is a whole number, then 2 and 1,694,237.5 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 | 3,388,475 | |
| -1 | -3,388,475 |
Now, we try dividing 3,388,475 by 3:
3,388,475 ÷ 3 = 1,129,491.6667
If the quotient is a whole number, then 3 and 1,129,491.6667 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 | 3,388,475 | |
| -1 | -3,388,475 |
Let's try dividing by 4:
3,388,475 ÷ 4 = 847,118.75
If the quotient is a whole number, then 4 and 847,118.75 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 | 3,388,475 | |
| -1 | 3,388,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 71 | 83 | 115 | 355 | 415 | 575 | 1,633 | 1,775 | 1,909 | 2,075 | 5,893 | 8,165 | 9,545 | 29,465 | 40,825 | 47,725 | 135,539 | 147,325 | 677,695 | 3,388,475 |
| -1 | -5 | -23 | -25 | -71 | -83 | -115 | -355 | -415 | -575 | -1,633 | -1,775 | -1,909 | -2,075 | -5,893 | -8,165 | -9,545 | -29,465 | -40,825 | -47,725 | -135,539 | -147,325 | -677,695 | -3,388,475 |
