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 22,585,129, 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 | 22,585,129 | |
| -1 | -22,585,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,585,129.
Example:
1 x 22,585,129 = 22,585,129
and
-1 x -22,585,129 = 22,585,129
Notice both answers equal 22,585,129
With that explanation out of the way, let's continue. Next, we take the number 22,585,129 and divide it by 2:
22,585,129 ÷ 2 = 11,292,564.5
If the quotient is a whole number, then 2 and 11,292,564.5 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 | 22,585,129 | |
| -1 | -22,585,129 |
Now, we try dividing 22,585,129 by 3:
22,585,129 ÷ 3 = 7,528,376.3333
If the quotient is a whole number, then 3 and 7,528,376.3333 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 | 22,585,129 | |
| -1 | -22,585,129 |
Let's try dividing by 4:
22,585,129 ÷ 4 = 5,646,282.25
If the quotient is a whole number, then 4 and 5,646,282.25 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 | 22,585,129 | |
| -1 | 22,585,129 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 49 | 119 | 133 | 323 | 833 | 931 | 1,427 | 2,261 | 9,989 | 15,827 | 24,259 | 27,113 | 69,923 | 169,813 | 189,791 | 460,921 | 1,188,691 | 1,328,537 | 3,226,447 | 22,585,129 |
| -1 | -7 | -17 | -19 | -49 | -119 | -133 | -323 | -833 | -931 | -1,427 | -2,261 | -9,989 | -15,827 | -24,259 | -27,113 | -69,923 | -169,813 | -189,791 | -460,921 | -1,188,691 | -1,328,537 | -3,226,447 | -22,585,129 |
