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 22,226,155, 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 | 22,226,155 | |
| -1 | -22,226,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,226,155.
Example:
1 x 22,226,155 = 22,226,155
and
-1 x -22,226,155 = 22,226,155
Notice both answers equal 22,226,155
With that explanation out of the way, let's continue. Next, we take the number 22,226,155 and divide it by 2:
22,226,155 ÷ 2 = 11,113,077.5
If the quotient is a whole number, then 2 and 11,113,077.5 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 | 22,226,155 | |
| -1 | -22,226,155 |
Now, we try dividing 22,226,155 by 3:
22,226,155 ÷ 3 = 7,408,718.3333
If the quotient is a whole number, then 3 and 7,408,718.3333 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 | 22,226,155 | |
| -1 | -22,226,155 |
Let's try dividing by 4:
22,226,155 ÷ 4 = 5,556,538.75
If the quotient is a whole number, then 4 and 5,556,538.75 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 | 22,226,155 | |
| -1 | 22,226,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 83 | 245 | 415 | 581 | 1,093 | 2,905 | 4,067 | 5,465 | 7,651 | 20,335 | 38,255 | 53,557 | 90,719 | 267,785 | 453,595 | 635,033 | 3,175,165 | 4,445,231 | 22,226,155 |
| -1 | -5 | -7 | -35 | -49 | -83 | -245 | -415 | -581 | -1,093 | -2,905 | -4,067 | -5,465 | -7,651 | -20,335 | -38,255 | -53,557 | -90,719 | -267,785 | -453,595 | -635,033 | -3,175,165 | -4,445,231 | -22,226,155 |
