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 7,822,535, 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 | 7,822,535 | |
| -1 | -7,822,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,822,535.
Example:
1 x 7,822,535 = 7,822,535
and
-1 x -7,822,535 = 7,822,535
Notice both answers equal 7,822,535
With that explanation out of the way, let's continue. Next, we take the number 7,822,535 and divide it by 2:
7,822,535 ÷ 2 = 3,911,267.5
If the quotient is a whole number, then 2 and 3,911,267.5 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 | 7,822,535 | |
| -1 | -7,822,535 |
Now, we try dividing 7,822,535 by 3:
7,822,535 ÷ 3 = 2,607,511.6667
If the quotient is a whole number, then 3 and 2,607,511.6667 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 | 7,822,535 | |
| -1 | -7,822,535 |
Let's try dividing by 4:
7,822,535 ÷ 4 = 1,955,633.75
If the quotient is a whole number, then 4 and 1,955,633.75 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 | 7,822,535 | |
| -1 | 7,822,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 4,217 | 21,085 | 29,519 | 147,595 | 223,501 | 1,117,505 | 1,564,507 | 7,822,535 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -4,217 | -21,085 | -29,519 | -147,595 | -223,501 | -1,117,505 | -1,564,507 | -7,822,535 |
