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 29,716,589, 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 | 29,716,589 | |
| -1 | -29,716,589 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,716,589.
Example:
1 x 29,716,589 = 29,716,589
and
-1 x -29,716,589 = 29,716,589
Notice both answers equal 29,716,589
With that explanation out of the way, let's continue. Next, we take the number 29,716,589 and divide it by 2:
29,716,589 ÷ 2 = 14,858,294.5
If the quotient is a whole number, then 2 and 14,858,294.5 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 | 29,716,589 | |
| -1 | -29,716,589 |
Now, we try dividing 29,716,589 by 3:
29,716,589 ÷ 3 = 9,905,529.6667
If the quotient is a whole number, then 3 and 9,905,529.6667 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 | 29,716,589 | |
| -1 | -29,716,589 |
Let's try dividing by 4:
29,716,589 ÷ 4 = 7,429,147.25
If the quotient is a whole number, then 4 and 7,429,147.25 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 | 29,716,589 | |
| -1 | 29,716,589 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 59 | 133 | 413 | 541 | 931 | 1,121 | 2,891 | 3,787 | 7,847 | 10,279 | 26,509 | 31,919 | 54,929 | 71,953 | 223,433 | 503,671 | 606,461 | 1,564,031 | 4,245,227 | 29,716,589 |
| -1 | -7 | -19 | -49 | -59 | -133 | -413 | -541 | -931 | -1,121 | -2,891 | -3,787 | -7,847 | -10,279 | -26,509 | -31,919 | -54,929 | -71,953 | -223,433 | -503,671 | -606,461 | -1,564,031 | -4,245,227 | -29,716,589 |
