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 3,336,515, 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 | 3,336,515 | |
| -1 | -3,336,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,336,515.
Example:
1 x 3,336,515 = 3,336,515
and
-1 x -3,336,515 = 3,336,515
Notice both answers equal 3,336,515
With that explanation out of the way, let's continue. Next, we take the number 3,336,515 and divide it by 2:
3,336,515 ÷ 2 = 1,668,257.5
If the quotient is a whole number, then 2 and 1,668,257.5 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 | 3,336,515 | |
| -1 | -3,336,515 |
Now, we try dividing 3,336,515 by 3:
3,336,515 ÷ 3 = 1,112,171.6667
If the quotient is a whole number, then 3 and 1,112,171.6667 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 | 3,336,515 | |
| -1 | -3,336,515 |
Let's try dividing by 4:
3,336,515 ÷ 4 = 834,128.75
If the quotient is a whole number, then 4 and 834,128.75 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 | 3,336,515 | |
| -1 | 3,336,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 7,333 | 36,665 | 51,331 | 95,329 | 256,655 | 476,645 | 667,303 | 3,336,515 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -7,333 | -36,665 | -51,331 | -95,329 | -256,655 | -476,645 | -667,303 | -3,336,515 |
