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 29,004,745, 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 | 29,004,745 | |
| -1 | -29,004,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,004,745.
Example:
1 x 29,004,745 = 29,004,745
and
-1 x -29,004,745 = 29,004,745
Notice both answers equal 29,004,745
With that explanation out of the way, let's continue. Next, we take the number 29,004,745 and divide it by 2:
29,004,745 ÷ 2 = 14,502,372.5
If the quotient is a whole number, then 2 and 14,502,372.5 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 | 29,004,745 | |
| -1 | -29,004,745 |
Now, we try dividing 29,004,745 by 3:
29,004,745 ÷ 3 = 9,668,248.3333
If the quotient is a whole number, then 3 and 9,668,248.3333 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 | 29,004,745 | |
| -1 | -29,004,745 |
Let's try dividing by 4:
29,004,745 ÷ 4 = 7,251,186.25
If the quotient is a whole number, then 4 and 7,251,186.25 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 | 29,004,745 | |
| -1 | 29,004,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 75,337 | 376,685 | 527,359 | 828,707 | 2,636,795 | 4,143,535 | 5,800,949 | 29,004,745 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -75,337 | -376,685 | -527,359 | -828,707 | -2,636,795 | -4,143,535 | -5,800,949 | -29,004,745 |
