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 7,200,613, 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 | 7,200,613 | |
| -1 | -7,200,613 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,200,613.
Example:
1 x 7,200,613 = 7,200,613
and
-1 x -7,200,613 = 7,200,613
Notice both answers equal 7,200,613
With that explanation out of the way, let's continue. Next, we take the number 7,200,613 and divide it by 2:
7,200,613 ÷ 2 = 3,600,306.5
If the quotient is a whole number, then 2 and 3,600,306.5 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 | 7,200,613 | |
| -1 | -7,200,613 |
Now, we try dividing 7,200,613 by 3:
7,200,613 ÷ 3 = 2,400,204.3333
If the quotient is a whole number, then 3 and 2,400,204.3333 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 | 7,200,613 | |
| -1 | -7,200,613 |
Let's try dividing by 4:
7,200,613 ÷ 4 = 1,800,153.25
If the quotient is a whole number, then 4 and 1,800,153.25 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 | 7,200,613 | |
| -1 | 7,200,613 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 79 | 203 | 449 | 553 | 2,291 | 3,143 | 13,021 | 16,037 | 35,471 | 91,147 | 248,297 | 1,028,659 | 7,200,613 |
| -1 | -7 | -29 | -79 | -203 | -449 | -553 | -2,291 | -3,143 | -13,021 | -16,037 | -35,471 | -91,147 | -248,297 | -1,028,659 | -7,200,613 |
