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 29,654,821, 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 | 29,654,821 | |
| -1 | -29,654,821 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,654,821.
Example:
1 x 29,654,821 = 29,654,821
and
-1 x -29,654,821 = 29,654,821
Notice both answers equal 29,654,821
With that explanation out of the way, let's continue. Next, we take the number 29,654,821 and divide it by 2:
29,654,821 ÷ 2 = 14,827,410.5
If the quotient is a whole number, then 2 and 14,827,410.5 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 | 29,654,821 | |
| -1 | -29,654,821 |
Now, we try dividing 29,654,821 by 3:
29,654,821 ÷ 3 = 9,884,940.3333
If the quotient is a whole number, then 3 and 9,884,940.3333 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 | 29,654,821 | |
| -1 | -29,654,821 |
Let's try dividing by 4:
29,654,821 ÷ 4 = 7,413,705.25
If the quotient is a whole number, then 4 and 7,413,705.25 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 | 29,654,821 | |
| -1 | 29,654,821 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 83 | 301 | 581 | 1,187 | 3,569 | 8,309 | 24,983 | 51,041 | 98,521 | 357,287 | 689,647 | 4,236,403 | 29,654,821 |
| -1 | -7 | -43 | -83 | -301 | -581 | -1,187 | -3,569 | -8,309 | -24,983 | -51,041 | -98,521 | -357,287 | -689,647 | -4,236,403 | -29,654,821 |
