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 29,756,227, 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 | 29,756,227 | |
| -1 | -29,756,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,756,227.
Example:
1 x 29,756,227 = 29,756,227
and
-1 x -29,756,227 = 29,756,227
Notice both answers equal 29,756,227
With that explanation out of the way, let's continue. Next, we take the number 29,756,227 and divide it by 2:
29,756,227 ÷ 2 = 14,878,113.5
If the quotient is a whole number, then 2 and 14,878,113.5 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 | 29,756,227 | |
| -1 | -29,756,227 |
Now, we try dividing 29,756,227 by 3:
29,756,227 ÷ 3 = 9,918,742.3333
If the quotient is a whole number, then 3 and 9,918,742.3333 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 | 29,756,227 | |
| -1 | -29,756,227 |
Let's try dividing by 4:
29,756,227 ÷ 4 = 7,439,056.75
If the quotient is a whole number, then 4 and 7,439,056.75 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 | 29,756,227 | |
| -1 | 29,756,227 |
If you did it right, you will end up with this table:
| 1 | 23 | 61 | 127 | 167 | 1,403 | 2,921 | 3,841 | 7,747 | 10,187 | 21,209 | 178,181 | 234,301 | 487,807 | 1,293,749 | 29,756,227 |
| -1 | -23 | -61 | -127 | -167 | -1,403 | -2,921 | -3,841 | -7,747 | -10,187 | -21,209 | -178,181 | -234,301 | -487,807 | -1,293,749 | -29,756,227 |
