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 234,542,143, 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 | 234,542,143 | |
| -1 | -234,542,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,542,143.
Example:
1 x 234,542,143 = 234,542,143
and
-1 x -234,542,143 = 234,542,143
Notice both answers equal 234,542,143
With that explanation out of the way, let's continue. Next, we take the number 234,542,143 and divide it by 2:
234,542,143 ÷ 2 = 117,271,071.5
If the quotient is a whole number, then 2 and 117,271,071.5 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 | 234,542,143 | |
| -1 | -234,542,143 |
Now, we try dividing 234,542,143 by 3:
234,542,143 ÷ 3 = 78,180,714.3333
If the quotient is a whole number, then 3 and 78,180,714.3333 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 | 234,542,143 | |
| -1 | -234,542,143 |
Let's try dividing by 4:
234,542,143 ÷ 4 = 58,635,535.75
If the quotient is a whole number, then 4 and 58,635,535.75 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 | 234,542,143 | |
| -1 | 234,542,143 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 157 | 737 | 1,727 | 2,027 | 10,519 | 22,297 | 115,709 | 135,809 | 318,239 | 1,493,899 | 3,500,629 | 21,322,013 | 234,542,143 |
| -1 | -11 | -67 | -157 | -737 | -1,727 | -2,027 | -10,519 | -22,297 | -115,709 | -135,809 | -318,239 | -1,493,899 | -3,500,629 | -21,322,013 | -234,542,143 |
