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 29,711,885, 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 | 29,711,885 | |
| -1 | -29,711,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,711,885.
Example:
1 x 29,711,885 = 29,711,885
and
-1 x -29,711,885 = 29,711,885
Notice both answers equal 29,711,885
With that explanation out of the way, let's continue. Next, we take the number 29,711,885 and divide it by 2:
29,711,885 ÷ 2 = 14,855,942.5
If the quotient is a whole number, then 2 and 14,855,942.5 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 | 29,711,885 | |
| -1 | -29,711,885 |
Now, we try dividing 29,711,885 by 3:
29,711,885 ÷ 3 = 9,903,961.6667
If the quotient is a whole number, then 3 and 9,903,961.6667 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 | 29,711,885 | |
| -1 | -29,711,885 |
Let's try dividing by 4:
29,711,885 ÷ 4 = 7,427,971.25
If the quotient is a whole number, then 4 and 7,427,971.25 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 | 29,711,885 | |
| -1 | 29,711,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 173 | 245 | 701 | 865 | 1,211 | 3,505 | 4,907 | 6,055 | 8,477 | 24,535 | 34,349 | 42,385 | 121,273 | 171,745 | 606,365 | 848,911 | 4,244,555 | 5,942,377 | 29,711,885 |
| -1 | -5 | -7 | -35 | -49 | -173 | -245 | -701 | -865 | -1,211 | -3,505 | -4,907 | -6,055 | -8,477 | -24,535 | -34,349 | -42,385 | -121,273 | -171,745 | -606,365 | -848,911 | -4,244,555 | -5,942,377 | -29,711,885 |
