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 7,240,595, 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 | 7,240,595 | |
| -1 | -7,240,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,240,595.
Example:
1 x 7,240,595 = 7,240,595
and
-1 x -7,240,595 = 7,240,595
Notice both answers equal 7,240,595
With that explanation out of the way, let's continue. Next, we take the number 7,240,595 and divide it by 2:
7,240,595 ÷ 2 = 3,620,297.5
If the quotient is a whole number, then 2 and 3,620,297.5 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 | 7,240,595 | |
| -1 | -7,240,595 |
Now, we try dividing 7,240,595 by 3:
7,240,595 ÷ 3 = 2,413,531.6667
If the quotient is a whole number, then 3 and 2,413,531.6667 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 | 7,240,595 | |
| -1 | -7,240,595 |
Let's try dividing by 4:
7,240,595 ÷ 4 = 1,810,148.75
If the quotient is a whole number, then 4 and 1,810,148.75 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 | 7,240,595 | |
| -1 | 7,240,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 89 | 265 | 307 | 445 | 1,535 | 4,717 | 16,271 | 23,585 | 27,323 | 81,355 | 136,615 | 1,448,119 | 7,240,595 |
| -1 | -5 | -53 | -89 | -265 | -307 | -445 | -1,535 | -4,717 | -16,271 | -23,585 | -27,323 | -81,355 | -136,615 | -1,448,119 | -7,240,595 |
