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 234,150,281, 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 | 234,150,281 | |
| -1 | -234,150,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,150,281.
Example:
1 x 234,150,281 = 234,150,281
and
-1 x -234,150,281 = 234,150,281
Notice both answers equal 234,150,281
With that explanation out of the way, let's continue. Next, we take the number 234,150,281 and divide it by 2:
234,150,281 ÷ 2 = 117,075,140.5
If the quotient is a whole number, then 2 and 117,075,140.5 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 | 234,150,281 | |
| -1 | -234,150,281 |
Now, we try dividing 234,150,281 by 3:
234,150,281 ÷ 3 = 78,050,093.6667
If the quotient is a whole number, then 3 and 78,050,093.6667 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 | 234,150,281 | |
| -1 | -234,150,281 |
Let's try dividing by 4:
234,150,281 ÷ 4 = 58,537,570.25
If the quotient is a whole number, then 4 and 58,537,570.25 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 | 234,150,281 | |
| -1 | 234,150,281 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 127 | 437 | 2,413 | 2,921 | 4,219 | 55,499 | 80,161 | 97,037 | 535,813 | 1,843,703 | 10,180,447 | 12,323,699 | 234,150,281 |
| -1 | -19 | -23 | -127 | -437 | -2,413 | -2,921 | -4,219 | -55,499 | -80,161 | -97,037 | -535,813 | -1,843,703 | -10,180,447 | -12,323,699 | -234,150,281 |
