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 3,655,729, 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 | 3,655,729 | |
| -1 | -3,655,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,655,729.
Example:
1 x 3,655,729 = 3,655,729
and
-1 x -3,655,729 = 3,655,729
Notice both answers equal 3,655,729
With that explanation out of the way, let's continue. Next, we take the number 3,655,729 and divide it by 2:
3,655,729 ÷ 2 = 1,827,864.5
If the quotient is a whole number, then 2 and 1,827,864.5 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 | 3,655,729 | |
| -1 | -3,655,729 |
Now, we try dividing 3,655,729 by 3:
3,655,729 ÷ 3 = 1,218,576.3333
If the quotient is a whole number, then 3 and 1,218,576.3333 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 | 3,655,729 | |
| -1 | -3,655,729 |
Let's try dividing by 4:
3,655,729 ÷ 4 = 913,932.25
If the quotient is a whole number, then 4 and 913,932.25 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 | 3,655,729 | |
| -1 | 3,655,729 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 197 | 241 | 1,379 | 1,687 | 2,167 | 2,651 | 15,169 | 18,557 | 47,477 | 332,339 | 522,247 | 3,655,729 |
| -1 | -7 | -11 | -77 | -197 | -241 | -1,379 | -1,687 | -2,167 | -2,651 | -15,169 | -18,557 | -47,477 | -332,339 | -522,247 | -3,655,729 |
