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 14,314,781, 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 | 14,314,781 | |
| -1 | -14,314,781 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,314,781.
Example:
1 x 14,314,781 = 14,314,781
and
-1 x -14,314,781 = 14,314,781
Notice both answers equal 14,314,781
With that explanation out of the way, let's continue. Next, we take the number 14,314,781 and divide it by 2:
14,314,781 ÷ 2 = 7,157,390.5
If the quotient is a whole number, then 2 and 7,157,390.5 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 | 14,314,781 | |
| -1 | -14,314,781 |
Now, we try dividing 14,314,781 by 3:
14,314,781 ÷ 3 = 4,771,593.6667
If the quotient is a whole number, then 3 and 4,771,593.6667 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 | 14,314,781 | |
| -1 | -14,314,781 |
Let's try dividing by 4:
14,314,781 ÷ 4 = 3,578,695.25
If the quotient is a whole number, then 4 and 3,578,695.25 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 | 14,314,781 | |
| -1 | 14,314,781 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 107 | 251 | 533 | 1,391 | 3,263 | 4,387 | 10,291 | 26,857 | 57,031 | 133,783 | 349,141 | 1,101,137 | 14,314,781 |
| -1 | -13 | -41 | -107 | -251 | -533 | -1,391 | -3,263 | -4,387 | -10,291 | -26,857 | -57,031 | -133,783 | -349,141 | -1,101,137 | -14,314,781 |
