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 22,404,515, 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 | 22,404,515 | |
| -1 | -22,404,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,404,515.
Example:
1 x 22,404,515 = 22,404,515
and
-1 x -22,404,515 = 22,404,515
Notice both answers equal 22,404,515
With that explanation out of the way, let's continue. Next, we take the number 22,404,515 and divide it by 2:
22,404,515 ÷ 2 = 11,202,257.5
If the quotient is a whole number, then 2 and 11,202,257.5 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 | 22,404,515 | |
| -1 | -22,404,515 |
Now, we try dividing 22,404,515 by 3:
22,404,515 ÷ 3 = 7,468,171.6667
If the quotient is a whole number, then 3 and 7,468,171.6667 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 | 22,404,515 | |
| -1 | -22,404,515 |
Let's try dividing by 4:
22,404,515 ÷ 4 = 5,601,128.75
If the quotient is a whole number, then 4 and 5,601,128.75 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 | 22,404,515 | |
| -1 | 22,404,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 245 | 665 | 931 | 4,655 | 4,813 | 24,065 | 33,691 | 91,447 | 168,455 | 235,837 | 457,235 | 640,129 | 1,179,185 | 3,200,645 | 4,480,903 | 22,404,515 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -245 | -665 | -931 | -4,655 | -4,813 | -24,065 | -33,691 | -91,447 | -168,455 | -235,837 | -457,235 | -640,129 | -1,179,185 | -3,200,645 | -4,480,903 | -22,404,515 |
