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 7,288,435, 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 | 7,288,435 | |
| -1 | -7,288,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,288,435.
Example:
1 x 7,288,435 = 7,288,435
and
-1 x -7,288,435 = 7,288,435
Notice both answers equal 7,288,435
With that explanation out of the way, let's continue. Next, we take the number 7,288,435 and divide it by 2:
7,288,435 ÷ 2 = 3,644,217.5
If the quotient is a whole number, then 2 and 3,644,217.5 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 | 7,288,435 | |
| -1 | -7,288,435 |
Now, we try dividing 7,288,435 by 3:
7,288,435 ÷ 3 = 2,429,478.3333
If the quotient is a whole number, then 3 and 2,429,478.3333 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 | 7,288,435 | |
| -1 | -7,288,435 |
Let's try dividing by 4:
7,288,435 ÷ 4 = 1,822,108.75
If the quotient is a whole number, then 4 and 1,822,108.75 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 | 7,288,435 | |
| -1 | 7,288,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 121 | 385 | 605 | 847 | 1,721 | 4,235 | 8,605 | 12,047 | 18,931 | 60,235 | 94,655 | 132,517 | 208,241 | 662,585 | 1,041,205 | 1,457,687 | 7,288,435 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -121 | -385 | -605 | -847 | -1,721 | -4,235 | -8,605 | -12,047 | -18,931 | -60,235 | -94,655 | -132,517 | -208,241 | -662,585 | -1,041,205 | -1,457,687 | -7,288,435 |
