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 29,900,507, 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 | 29,900,507 | |
| -1 | -29,900,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,900,507.
Example:
1 x 29,900,507 = 29,900,507
and
-1 x -29,900,507 = 29,900,507
Notice both answers equal 29,900,507
With that explanation out of the way, let's continue. Next, we take the number 29,900,507 and divide it by 2:
29,900,507 ÷ 2 = 14,950,253.5
If the quotient is a whole number, then 2 and 14,950,253.5 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 | 29,900,507 | |
| -1 | -29,900,507 |
Now, we try dividing 29,900,507 by 3:
29,900,507 ÷ 3 = 9,966,835.6667
If the quotient is a whole number, then 3 and 9,966,835.6667 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 | 29,900,507 | |
| -1 | -29,900,507 |
Let's try dividing by 4:
29,900,507 ÷ 4 = 7,475,126.75
If the quotient is a whole number, then 4 and 7,475,126.75 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 | 29,900,507 | |
| -1 | 29,900,507 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 91 | 329 | 611 | 4,277 | 6,991 | 48,937 | 90,883 | 328,577 | 636,181 | 2,300,039 | 4,271,501 | 29,900,507 |
| -1 | -7 | -13 | -47 | -91 | -329 | -611 | -4,277 | -6,991 | -48,937 | -90,883 | -328,577 | -636,181 | -2,300,039 | -4,271,501 | -29,900,507 |
