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 14,222,165, 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 | 14,222,165 | |
| -1 | -14,222,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,222,165.
Example:
1 x 14,222,165 = 14,222,165
and
-1 x -14,222,165 = 14,222,165
Notice both answers equal 14,222,165
With that explanation out of the way, let's continue. Next, we take the number 14,222,165 and divide it by 2:
14,222,165 ÷ 2 = 7,111,082.5
If the quotient is a whole number, then 2 and 7,111,082.5 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 | 14,222,165 | |
| -1 | -14,222,165 |
Now, we try dividing 14,222,165 by 3:
14,222,165 ÷ 3 = 4,740,721.6667
If the quotient is a whole number, then 3 and 4,740,721.6667 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 | 14,222,165 | |
| -1 | -14,222,165 |
Let's try dividing by 4:
14,222,165 ÷ 4 = 3,555,541.25
If the quotient is a whole number, then 4 and 3,555,541.25 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 | 14,222,165 | |
| -1 | 14,222,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 283 | 437 | 529 | 1,415 | 2,185 | 2,645 | 5,377 | 6,509 | 10,051 | 26,885 | 32,545 | 50,255 | 123,671 | 149,707 | 618,355 | 748,535 | 2,844,433 | 14,222,165 |
| -1 | -5 | -19 | -23 | -95 | -115 | -283 | -437 | -529 | -1,415 | -2,185 | -2,645 | -5,377 | -6,509 | -10,051 | -26,885 | -32,545 | -50,255 | -123,671 | -149,707 | -618,355 | -748,535 | -2,844,433 | -14,222,165 |
