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 22,100,375, 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 | 22,100,375 | |
| -1 | -22,100,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,100,375.
Example:
1 x 22,100,375 = 22,100,375
and
-1 x -22,100,375 = 22,100,375
Notice both answers equal 22,100,375
With that explanation out of the way, let's continue. Next, we take the number 22,100,375 and divide it by 2:
22,100,375 ÷ 2 = 11,050,187.5
If the quotient is a whole number, then 2 and 11,050,187.5 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 | 22,100,375 | |
| -1 | -22,100,375 |
Now, we try dividing 22,100,375 by 3:
22,100,375 ÷ 3 = 7,366,791.6667
If the quotient is a whole number, then 3 and 7,366,791.6667 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 | 22,100,375 | |
| -1 | -22,100,375 |
Let's try dividing by 4:
22,100,375 ÷ 4 = 5,525,093.75
If the quotient is a whole number, then 4 and 5,525,093.75 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 | 22,100,375 | |
| -1 | 22,100,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 16,073 | 80,365 | 176,803 | 401,825 | 884,015 | 2,009,125 | 4,420,075 | 22,100,375 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -16,073 | -80,365 | -176,803 | -401,825 | -884,015 | -2,009,125 | -4,420,075 | -22,100,375 |
