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 3,242,155, 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 | 3,242,155 | |
| -1 | -3,242,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,242,155.
Example:
1 x 3,242,155 = 3,242,155
and
-1 x -3,242,155 = 3,242,155
Notice both answers equal 3,242,155
With that explanation out of the way, let's continue. Next, we take the number 3,242,155 and divide it by 2:
3,242,155 ÷ 2 = 1,621,077.5
If the quotient is a whole number, then 2 and 1,621,077.5 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 | 3,242,155 | |
| -1 | -3,242,155 |
Now, we try dividing 3,242,155 by 3:
3,242,155 ÷ 3 = 1,080,718.3333
If the quotient is a whole number, then 3 and 1,080,718.3333 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 | 3,242,155 | |
| -1 | -3,242,155 |
Let's try dividing by 4:
3,242,155 ÷ 4 = 810,538.75
If the quotient is a whole number, then 4 and 810,538.75 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 | 3,242,155 | |
| -1 | 3,242,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 5,449 | 27,245 | 38,143 | 92,633 | 190,715 | 463,165 | 648,431 | 3,242,155 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -5,449 | -27,245 | -38,143 | -92,633 | -190,715 | -463,165 | -648,431 | -3,242,155 |
