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 234,151,225, 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 | 234,151,225 | |
| -1 | -234,151,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,151,225.
Example:
1 x 234,151,225 = 234,151,225
and
-1 x -234,151,225 = 234,151,225
Notice both answers equal 234,151,225
With that explanation out of the way, let's continue. Next, we take the number 234,151,225 and divide it by 2:
234,151,225 ÷ 2 = 117,075,612.5
If the quotient is a whole number, then 2 and 117,075,612.5 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 | 234,151,225 | |
| -1 | -234,151,225 |
Now, we try dividing 234,151,225 by 3:
234,151,225 ÷ 3 = 78,050,408.3333
If the quotient is a whole number, then 3 and 78,050,408.3333 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 | 234,151,225 | |
| -1 | -234,151,225 |
Let's try dividing by 4:
234,151,225 ÷ 4 = 58,537,806.25
If the quotient is a whole number, then 4 and 58,537,806.25 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 | 234,151,225 | |
| -1 | 234,151,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 121,637 | 608,185 | 851,459 | 1,338,007 | 3,040,925 | 4,257,295 | 6,690,035 | 9,366,049 | 21,286,475 | 33,450,175 | 46,830,245 | 234,151,225 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -121,637 | -608,185 | -851,459 | -1,338,007 | -3,040,925 | -4,257,295 | -6,690,035 | -9,366,049 | -21,286,475 | -33,450,175 | -46,830,245 | -234,151,225 |
