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 22,142,435, 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 | 22,142,435 | |
| -1 | -22,142,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,142,435.
Example:
1 x 22,142,435 = 22,142,435
and
-1 x -22,142,435 = 22,142,435
Notice both answers equal 22,142,435
With that explanation out of the way, let's continue. Next, we take the number 22,142,435 and divide it by 2:
22,142,435 ÷ 2 = 11,071,217.5
If the quotient is a whole number, then 2 and 11,071,217.5 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 | 22,142,435 | |
| -1 | -22,142,435 |
Now, we try dividing 22,142,435 by 3:
22,142,435 ÷ 3 = 7,380,811.6667
If the quotient is a whole number, then 3 and 7,380,811.6667 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 | 22,142,435 | |
| -1 | -22,142,435 |
Let's try dividing by 4:
22,142,435 ÷ 4 = 5,535,608.75
If the quotient is a whole number, then 4 and 5,535,608.75 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 | 22,142,435 | |
| -1 | 22,142,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 449 | 1,409 | 2,245 | 3,143 | 7,045 | 9,863 | 15,715 | 49,315 | 632,641 | 3,163,205 | 4,428,487 | 22,142,435 |
| -1 | -5 | -7 | -35 | -449 | -1,409 | -2,245 | -3,143 | -7,045 | -9,863 | -15,715 | -49,315 | -632,641 | -3,163,205 | -4,428,487 | -22,142,435 |
