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 3,216,395, 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 | 3,216,395 | |
| -1 | -3,216,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,216,395.
Example:
1 x 3,216,395 = 3,216,395
and
-1 x -3,216,395 = 3,216,395
Notice both answers equal 3,216,395
With that explanation out of the way, let's continue. Next, we take the number 3,216,395 and divide it by 2:
3,216,395 ÷ 2 = 1,608,197.5
If the quotient is a whole number, then 2 and 1,608,197.5 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 | 3,216,395 | |
| -1 | -3,216,395 |
Now, we try dividing 3,216,395 by 3:
3,216,395 ÷ 3 = 1,072,131.6667
If the quotient is a whole number, then 3 and 1,072,131.6667 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 | 3,216,395 | |
| -1 | -3,216,395 |
Let's try dividing by 4:
3,216,395 ÷ 4 = 804,098.75
If the quotient is a whole number, then 4 and 804,098.75 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 | 3,216,395 | |
| -1 | 3,216,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 7,069 | 35,345 | 49,483 | 91,897 | 247,415 | 459,485 | 643,279 | 3,216,395 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -7,069 | -35,345 | -49,483 | -91,897 | -247,415 | -459,485 | -643,279 | -3,216,395 |
