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 3,242,225, 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 | 3,242,225 | |
| -1 | -3,242,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,242,225.
Example:
1 x 3,242,225 = 3,242,225
and
-1 x -3,242,225 = 3,242,225
Notice both answers equal 3,242,225
With that explanation out of the way, let's continue. Next, we take the number 3,242,225 and divide it by 2:
3,242,225 ÷ 2 = 1,621,112.5
If the quotient is a whole number, then 2 and 1,621,112.5 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 | 3,242,225 | |
| -1 | -3,242,225 |
Now, we try dividing 3,242,225 by 3:
3,242,225 ÷ 3 = 1,080,741.6667
If the quotient is a whole number, then 3 and 1,080,741.6667 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 | 3,242,225 | |
| -1 | -3,242,225 |
Let's try dividing by 4:
3,242,225 ÷ 4 = 810,556.25
If the quotient is a whole number, then 4 and 810,556.25 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 | 3,242,225 | |
| -1 | 3,242,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 97 | 175 | 191 | 485 | 679 | 955 | 1,337 | 2,425 | 3,395 | 4,775 | 6,685 | 16,975 | 18,527 | 33,425 | 92,635 | 129,689 | 463,175 | 648,445 | 3,242,225 |
| -1 | -5 | -7 | -25 | -35 | -97 | -175 | -191 | -485 | -679 | -955 | -1,337 | -2,425 | -3,395 | -4,775 | -6,685 | -16,975 | -18,527 | -33,425 | -92,635 | -129,689 | -463,175 | -648,445 | -3,242,225 |
