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 22,167,475, 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 | 22,167,475 | |
| -1 | -22,167,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,167,475.
Example:
1 x 22,167,475 = 22,167,475
and
-1 x -22,167,475 = 22,167,475
Notice both answers equal 22,167,475
With that explanation out of the way, let's continue. Next, we take the number 22,167,475 and divide it by 2:
22,167,475 ÷ 2 = 11,083,737.5
If the quotient is a whole number, then 2 and 11,083,737.5 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 | 22,167,475 | |
| -1 | -22,167,475 |
Now, we try dividing 22,167,475 by 3:
22,167,475 ÷ 3 = 7,389,158.3333
If the quotient is a whole number, then 3 and 7,389,158.3333 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 | 22,167,475 | |
| -1 | -22,167,475 |
Let's try dividing by 4:
22,167,475 ÷ 4 = 5,541,868.75
If the quotient is a whole number, then 4 and 5,541,868.75 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 | 22,167,475 | |
| -1 | 22,167,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 149 | 275 | 541 | 745 | 1,639 | 2,705 | 3,725 | 5,951 | 8,195 | 13,525 | 29,755 | 40,975 | 80,609 | 148,775 | 403,045 | 886,699 | 2,015,225 | 4,433,495 | 22,167,475 |
| -1 | -5 | -11 | -25 | -55 | -149 | -275 | -541 | -745 | -1,639 | -2,705 | -3,725 | -5,951 | -8,195 | -13,525 | -29,755 | -40,975 | -80,609 | -148,775 | -403,045 | -886,699 | -2,015,225 | -4,433,495 | -22,167,475 |
