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 22,142,399, 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 | 22,142,399 | |
| -1 | -22,142,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,142,399.
Example:
1 x 22,142,399 = 22,142,399
and
-1 x -22,142,399 = 22,142,399
Notice both answers equal 22,142,399
With that explanation out of the way, let's continue. Next, we take the number 22,142,399 and divide it by 2:
22,142,399 ÷ 2 = 11,071,199.5
If the quotient is a whole number, then 2 and 11,071,199.5 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 | 22,142,399 | |
| -1 | -22,142,399 |
Now, we try dividing 22,142,399 by 3:
22,142,399 ÷ 3 = 7,380,799.6667
If the quotient is a whole number, then 3 and 7,380,799.6667 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 | 22,142,399 | |
| -1 | -22,142,399 |
Let's try dividing by 4:
22,142,399 ÷ 4 = 5,535,599.75
If the quotient is a whole number, then 4 and 5,535,599.75 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 | 22,142,399 | |
| -1 | 22,142,399 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 89 | 373 | 667 | 2,047 | 2,581 | 8,579 | 10,817 | 33,197 | 59,363 | 248,791 | 763,531 | 962,713 | 22,142,399 |
| -1 | -23 | -29 | -89 | -373 | -667 | -2,047 | -2,581 | -8,579 | -10,817 | -33,197 | -59,363 | -248,791 | -763,531 | -962,713 | -22,142,399 |
