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 16,335,739, 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 | 16,335,739 | |
| -1 | -16,335,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,335,739.
Example:
1 x 16,335,739 = 16,335,739
and
-1 x -16,335,739 = 16,335,739
Notice both answers equal 16,335,739
With that explanation out of the way, let's continue. Next, we take the number 16,335,739 and divide it by 2:
16,335,739 ÷ 2 = 8,167,869.5
If the quotient is a whole number, then 2 and 8,167,869.5 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 | 16,335,739 | |
| -1 | -16,335,739 |
Now, we try dividing 16,335,739 by 3:
16,335,739 ÷ 3 = 5,445,246.3333
If the quotient is a whole number, then 3 and 5,445,246.3333 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 | 16,335,739 | |
| -1 | -16,335,739 |
Let's try dividing by 4:
16,335,739 ÷ 4 = 4,083,934.75
If the quotient is a whole number, then 4 and 4,083,934.75 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 | 16,335,739 | |
| -1 | 16,335,739 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 67 | 427 | 469 | 571 | 3,997 | 4,087 | 28,609 | 34,831 | 38,257 | 243,817 | 267,799 | 2,333,677 | 16,335,739 |
| -1 | -7 | -61 | -67 | -427 | -469 | -571 | -3,997 | -4,087 | -28,609 | -34,831 | -38,257 | -243,817 | -267,799 | -2,333,677 | -16,335,739 |
