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 29,136,725, 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 | 29,136,725 | |
| -1 | -29,136,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,136,725.
Example:
1 x 29,136,725 = 29,136,725
and
-1 x -29,136,725 = 29,136,725
Notice both answers equal 29,136,725
With that explanation out of the way, let's continue. Next, we take the number 29,136,725 and divide it by 2:
29,136,725 ÷ 2 = 14,568,362.5
If the quotient is a whole number, then 2 and 14,568,362.5 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 | 29,136,725 | |
| -1 | -29,136,725 |
Now, we try dividing 29,136,725 by 3:
29,136,725 ÷ 3 = 9,712,241.6667
If the quotient is a whole number, then 3 and 9,712,241.6667 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 | 29,136,725 | |
| -1 | -29,136,725 |
Let's try dividing by 4:
29,136,725 ÷ 4 = 7,284,181.25
If the quotient is a whole number, then 4 and 7,284,181.25 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 | 29,136,725 | |
| -1 | 29,136,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 179 | 383 | 425 | 895 | 1,915 | 3,043 | 4,475 | 6,511 | 9,575 | 15,215 | 32,555 | 68,557 | 76,075 | 162,775 | 342,785 | 1,165,469 | 1,713,925 | 5,827,345 | 29,136,725 |
| -1 | -5 | -17 | -25 | -85 | -179 | -383 | -425 | -895 | -1,915 | -3,043 | -4,475 | -6,511 | -9,575 | -15,215 | -32,555 | -68,557 | -76,075 | -162,775 | -342,785 | -1,165,469 | -1,713,925 | -5,827,345 | -29,136,725 |
