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 29,026,129, 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 | 29,026,129 | |
| -1 | -29,026,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,026,129.
Example:
1 x 29,026,129 = 29,026,129
and
-1 x -29,026,129 = 29,026,129
Notice both answers equal 29,026,129
With that explanation out of the way, let's continue. Next, we take the number 29,026,129 and divide it by 2:
29,026,129 ÷ 2 = 14,513,064.5
If the quotient is a whole number, then 2 and 14,513,064.5 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 | 29,026,129 | |
| -1 | -29,026,129 |
Now, we try dividing 29,026,129 by 3:
29,026,129 ÷ 3 = 9,675,376.3333
If the quotient is a whole number, then 3 and 9,675,376.3333 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 | 29,026,129 | |
| -1 | -29,026,129 |
Let's try dividing by 4:
29,026,129 ÷ 4 = 7,256,532.25
If the quotient is a whole number, then 4 and 7,256,532.25 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 | 29,026,129 | |
| -1 | 29,026,129 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 29 | 209 | 319 | 551 | 4,789 | 6,061 | 52,679 | 90,991 | 138,881 | 1,000,901 | 1,527,691 | 2,638,739 | 29,026,129 |
| -1 | -11 | -19 | -29 | -209 | -319 | -551 | -4,789 | -6,061 | -52,679 | -90,991 | -138,881 | -1,000,901 | -1,527,691 | -2,638,739 | -29,026,129 |
