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 22,100,315, 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 | 22,100,315 | |
| -1 | -22,100,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,100,315.
Example:
1 x 22,100,315 = 22,100,315
and
-1 x -22,100,315 = 22,100,315
Notice both answers equal 22,100,315
With that explanation out of the way, let's continue. Next, we take the number 22,100,315 and divide it by 2:
22,100,315 ÷ 2 = 11,050,157.5
If the quotient is a whole number, then 2 and 11,050,157.5 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 | 22,100,315 | |
| -1 | -22,100,315 |
Now, we try dividing 22,100,315 by 3:
22,100,315 ÷ 3 = 7,366,771.6667
If the quotient is a whole number, then 3 and 7,366,771.6667 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 | 22,100,315 | |
| -1 | -22,100,315 |
Let's try dividing by 4:
22,100,315 ÷ 4 = 5,525,078.75
If the quotient is a whole number, then 4 and 5,525,078.75 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 | 22,100,315 | |
| -1 | 22,100,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 107 | 409 | 505 | 535 | 2,045 | 10,807 | 41,309 | 43,763 | 54,035 | 206,545 | 218,815 | 4,420,063 | 22,100,315 |
| -1 | -5 | -101 | -107 | -409 | -505 | -535 | -2,045 | -10,807 | -41,309 | -43,763 | -54,035 | -206,545 | -218,815 | -4,420,063 | -22,100,315 |
