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 7,723,135, 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 | 7,723,135 | |
| -1 | -7,723,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,723,135.
Example:
1 x 7,723,135 = 7,723,135
and
-1 x -7,723,135 = 7,723,135
Notice both answers equal 7,723,135
With that explanation out of the way, let's continue. Next, we take the number 7,723,135 and divide it by 2:
7,723,135 ÷ 2 = 3,861,567.5
If the quotient is a whole number, then 2 and 3,861,567.5 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 | 7,723,135 | |
| -1 | -7,723,135 |
Now, we try dividing 7,723,135 by 3:
7,723,135 ÷ 3 = 2,574,378.3333
If the quotient is a whole number, then 3 and 2,574,378.3333 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 | 7,723,135 | |
| -1 | -7,723,135 |
Let's try dividing by 4:
7,723,135 ÷ 4 = 1,930,783.75
If the quotient is a whole number, then 4 and 1,930,783.75 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 | 7,723,135 | |
| -1 | 7,723,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 49 | 145 | 203 | 245 | 1,015 | 1,087 | 1,421 | 5,435 | 7,105 | 7,609 | 31,523 | 38,045 | 53,263 | 157,615 | 220,661 | 266,315 | 1,103,305 | 1,544,627 | 7,723,135 |
| -1 | -5 | -7 | -29 | -35 | -49 | -145 | -203 | -245 | -1,015 | -1,087 | -1,421 | -5,435 | -7,105 | -7,609 | -31,523 | -38,045 | -53,263 | -157,615 | -220,661 | -266,315 | -1,103,305 | -1,544,627 | -7,723,135 |
