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 22,158,655, 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 | 22,158,655 | |
| -1 | -22,158,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,158,655.
Example:
1 x 22,158,655 = 22,158,655
and
-1 x -22,158,655 = 22,158,655
Notice both answers equal 22,158,655
With that explanation out of the way, let's continue. Next, we take the number 22,158,655 and divide it by 2:
22,158,655 ÷ 2 = 11,079,327.5
If the quotient is a whole number, then 2 and 11,079,327.5 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 | 22,158,655 | |
| -1 | -22,158,655 |
Now, we try dividing 22,158,655 by 3:
22,158,655 ÷ 3 = 7,386,218.3333
If the quotient is a whole number, then 3 and 7,386,218.3333 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 | 22,158,655 | |
| -1 | -22,158,655 |
Let's try dividing by 4:
22,158,655 ÷ 4 = 5,539,663.75
If the quotient is a whole number, then 4 and 5,539,663.75 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 | 22,158,655 | |
| -1 | 22,158,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 41 | 95 | 205 | 779 | 3,895 | 5,689 | 28,445 | 108,091 | 233,249 | 540,455 | 1,166,245 | 4,431,731 | 22,158,655 |
| -1 | -5 | -19 | -41 | -95 | -205 | -779 | -3,895 | -5,689 | -28,445 | -108,091 | -233,249 | -540,455 | -1,166,245 | -4,431,731 | -22,158,655 |
