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 14,420,705, 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 | 14,420,705 | |
| -1 | -14,420,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,420,705.
Example:
1 x 14,420,705 = 14,420,705
and
-1 x -14,420,705 = 14,420,705
Notice both answers equal 14,420,705
With that explanation out of the way, let's continue. Next, we take the number 14,420,705 and divide it by 2:
14,420,705 ÷ 2 = 7,210,352.5
If the quotient is a whole number, then 2 and 7,210,352.5 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 | 14,420,705 | |
| -1 | -14,420,705 |
Now, we try dividing 14,420,705 by 3:
14,420,705 ÷ 3 = 4,806,901.6667
If the quotient is a whole number, then 3 and 4,806,901.6667 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 | 14,420,705 | |
| -1 | -14,420,705 |
Let's try dividing by 4:
14,420,705 ÷ 4 = 3,605,176.25
If the quotient is a whole number, then 4 and 3,605,176.25 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 | 14,420,705 | |
| -1 | 14,420,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 793 | 3,637 | 3,965 | 18,185 | 47,281 | 221,857 | 236,405 | 1,109,285 | 2,884,141 | 14,420,705 |
| -1 | -5 | -13 | -61 | -65 | -305 | -793 | -3,637 | -3,965 | -18,185 | -47,281 | -221,857 | -236,405 | -1,109,285 | -2,884,141 | -14,420,705 |
