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 7,823,011, 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 | 7,823,011 | |
| -1 | -7,823,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,823,011.
Example:
1 x 7,823,011 = 7,823,011
and
-1 x -7,823,011 = 7,823,011
Notice both answers equal 7,823,011
With that explanation out of the way, let's continue. Next, we take the number 7,823,011 and divide it by 2:
7,823,011 ÷ 2 = 3,911,505.5
If the quotient is a whole number, then 2 and 3,911,505.5 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 | 7,823,011 | |
| -1 | -7,823,011 |
Now, we try dividing 7,823,011 by 3:
7,823,011 ÷ 3 = 2,607,670.3333
If the quotient is a whole number, then 3 and 2,607,670.3333 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 | 7,823,011 | |
| -1 | -7,823,011 |
Let's try dividing by 4:
7,823,011 ÷ 4 = 1,955,752.75
If the quotient is a whole number, then 4 and 1,955,752.75 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 | 7,823,011 | |
| -1 | 7,823,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 89 | 203 | 433 | 623 | 2,581 | 3,031 | 12,557 | 18,067 | 38,537 | 87,899 | 269,759 | 1,117,573 | 7,823,011 |
| -1 | -7 | -29 | -89 | -203 | -433 | -623 | -2,581 | -3,031 | -12,557 | -18,067 | -38,537 | -87,899 | -269,759 | -1,117,573 | -7,823,011 |
