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 14,020,435, 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 | 14,020,435 | |
| -1 | -14,020,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,020,435.
Example:
1 x 14,020,435 = 14,020,435
and
-1 x -14,020,435 = 14,020,435
Notice both answers equal 14,020,435
With that explanation out of the way, let's continue. Next, we take the number 14,020,435 and divide it by 2:
14,020,435 ÷ 2 = 7,010,217.5
If the quotient is a whole number, then 2 and 7,010,217.5 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 | 14,020,435 | |
| -1 | -14,020,435 |
Now, we try dividing 14,020,435 by 3:
14,020,435 ÷ 3 = 4,673,478.3333
If the quotient is a whole number, then 3 and 4,673,478.3333 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 | 14,020,435 | |
| -1 | -14,020,435 |
Let's try dividing by 4:
14,020,435 ÷ 4 = 3,505,108.75
If the quotient is a whole number, then 4 and 3,505,108.75 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 | 14,020,435 | |
| -1 | 14,020,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 19,609 | 98,045 | 215,699 | 254,917 | 1,078,495 | 1,274,585 | 2,804,087 | 14,020,435 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -19,609 | -98,045 | -215,699 | -254,917 | -1,078,495 | -1,274,585 | -2,804,087 | -14,020,435 |
