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 29,165,185, 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 | 29,165,185 | |
| -1 | -29,165,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,165,185.
Example:
1 x 29,165,185 = 29,165,185
and
-1 x -29,165,185 = 29,165,185
Notice both answers equal 29,165,185
With that explanation out of the way, let's continue. Next, we take the number 29,165,185 and divide it by 2:
29,165,185 ÷ 2 = 14,582,592.5
If the quotient is a whole number, then 2 and 14,582,592.5 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 | 29,165,185 | |
| -1 | -29,165,185 |
Now, we try dividing 29,165,185 by 3:
29,165,185 ÷ 3 = 9,721,728.3333
If the quotient is a whole number, then 3 and 9,721,728.3333 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 | 29,165,185 | |
| -1 | -29,165,185 |
Let's try dividing by 4:
29,165,185 ÷ 4 = 7,291,296.25
If the quotient is a whole number, then 4 and 7,291,296.25 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 | 29,165,185 | |
| -1 | 29,165,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 131 | 655 | 917 | 4,585 | 6,361 | 31,805 | 44,527 | 222,635 | 833,291 | 4,166,455 | 5,833,037 | 29,165,185 |
| -1 | -5 | -7 | -35 | -131 | -655 | -917 | -4,585 | -6,361 | -31,805 | -44,527 | -222,635 | -833,291 | -4,166,455 | -5,833,037 | -29,165,185 |
