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 29,143,235, 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 | 29,143,235 | |
| -1 | -29,143,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,143,235.
Example:
1 x 29,143,235 = 29,143,235
and
-1 x -29,143,235 = 29,143,235
Notice both answers equal 29,143,235
With that explanation out of the way, let's continue. Next, we take the number 29,143,235 and divide it by 2:
29,143,235 ÷ 2 = 14,571,617.5
If the quotient is a whole number, then 2 and 14,571,617.5 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 | 29,143,235 | |
| -1 | -29,143,235 |
Now, we try dividing 29,143,235 by 3:
29,143,235 ÷ 3 = 9,714,411.6667
If the quotient is a whole number, then 3 and 9,714,411.6667 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 | 29,143,235 | |
| -1 | -29,143,235 |
Let's try dividing by 4:
29,143,235 ÷ 4 = 7,285,808.75
If the quotient is a whole number, then 4 and 7,285,808.75 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 | 29,143,235 | |
| -1 | 29,143,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 2,035 | 14,321 | 71,605 | 157,531 | 529,877 | 787,655 | 2,649,385 | 5,828,647 | 29,143,235 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -2,035 | -14,321 | -71,605 | -157,531 | -529,877 | -787,655 | -2,649,385 | -5,828,647 | -29,143,235 |
