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 3,315,425, 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 | 3,315,425 | |
| -1 | -3,315,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,315,425.
Example:
1 x 3,315,425 = 3,315,425
and
-1 x -3,315,425 = 3,315,425
Notice both answers equal 3,315,425
With that explanation out of the way, let's continue. Next, we take the number 3,315,425 and divide it by 2:
3,315,425 ÷ 2 = 1,657,712.5
If the quotient is a whole number, then 2 and 1,657,712.5 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 | 3,315,425 | |
| -1 | -3,315,425 |
Now, we try dividing 3,315,425 by 3:
3,315,425 ÷ 3 = 1,105,141.6667
If the quotient is a whole number, then 3 and 1,105,141.6667 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 | 3,315,425 | |
| -1 | -3,315,425 |
Let's try dividing by 4:
3,315,425 ÷ 4 = 828,856.25
If the quotient is a whole number, then 4 and 828,856.25 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 | 3,315,425 | |
| -1 | 3,315,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 29 | 85 | 145 | 269 | 425 | 493 | 725 | 1,345 | 2,465 | 4,573 | 6,725 | 7,801 | 12,325 | 22,865 | 39,005 | 114,325 | 132,617 | 195,025 | 663,085 | 3,315,425 |
| -1 | -5 | -17 | -25 | -29 | -85 | -145 | -269 | -425 | -493 | -725 | -1,345 | -2,465 | -4,573 | -6,725 | -7,801 | -12,325 | -22,865 | -39,005 | -114,325 | -132,617 | -195,025 | -663,085 | -3,315,425 |
