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 14,245,147, 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 | 14,245,147 | |
| -1 | -14,245,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,245,147.
Example:
1 x 14,245,147 = 14,245,147
and
-1 x -14,245,147 = 14,245,147
Notice both answers equal 14,245,147
With that explanation out of the way, let's continue. Next, we take the number 14,245,147 and divide it by 2:
14,245,147 ÷ 2 = 7,122,573.5
If the quotient is a whole number, then 2 and 7,122,573.5 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 | 14,245,147 | |
| -1 | -14,245,147 |
Now, we try dividing 14,245,147 by 3:
14,245,147 ÷ 3 = 4,748,382.3333
If the quotient is a whole number, then 3 and 4,748,382.3333 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 | 14,245,147 | |
| -1 | -14,245,147 |
Let's try dividing by 4:
14,245,147 ÷ 4 = 3,561,286.75
If the quotient is a whole number, then 4 and 3,561,286.75 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 | 14,245,147 | |
| -1 | 14,245,147 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 73 | 427 | 457 | 511 | 3,199 | 4,453 | 27,877 | 31,171 | 33,361 | 195,139 | 233,527 | 2,035,021 | 14,245,147 |
| -1 | -7 | -61 | -73 | -427 | -457 | -511 | -3,199 | -4,453 | -27,877 | -31,171 | -33,361 | -195,139 | -233,527 | -2,035,021 | -14,245,147 |
