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 234,155,351, 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 | 234,155,351 | |
| -1 | -234,155,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,155,351.
Example:
1 x 234,155,351 = 234,155,351
and
-1 x -234,155,351 = 234,155,351
Notice both answers equal 234,155,351
With that explanation out of the way, let's continue. Next, we take the number 234,155,351 and divide it by 2:
234,155,351 ÷ 2 = 117,077,675.5
If the quotient is a whole number, then 2 and 117,077,675.5 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 | 234,155,351 | |
| -1 | -234,155,351 |
Now, we try dividing 234,155,351 by 3:
234,155,351 ÷ 3 = 78,051,783.6667
If the quotient is a whole number, then 3 and 78,051,783.6667 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 | 234,155,351 | |
| -1 | -234,155,351 |
Let's try dividing by 4:
234,155,351 ÷ 4 = 58,538,837.75
If the quotient is a whole number, then 4 and 58,538,837.75 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 | 234,155,351 | |
| -1 | 234,155,351 |
If you did it right, you will end up with this table:
| 1 | 37 | 89 | 211 | 337 | 3,293 | 7,807 | 12,469 | 18,779 | 29,993 | 71,107 | 694,823 | 1,109,741 | 2,630,959 | 6,328,523 | 234,155,351 |
| -1 | -37 | -89 | -211 | -337 | -3,293 | -7,807 | -12,469 | -18,779 | -29,993 | -71,107 | -694,823 | -1,109,741 | -2,630,959 | -6,328,523 | -234,155,351 |
