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 119,892,253, 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 | 119,892,253 | |
| -1 | -119,892,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 119,892,253.
Example:
1 x 119,892,253 = 119,892,253
and
-1 x -119,892,253 = 119,892,253
Notice both answers equal 119,892,253
With that explanation out of the way, let's continue. Next, we take the number 119,892,253 and divide it by 2:
119,892,253 ÷ 2 = 59,946,126.5
If the quotient is a whole number, then 2 and 59,946,126.5 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 | 119,892,253 | |
| -1 | -119,892,253 |
Now, we try dividing 119,892,253 by 3:
119,892,253 ÷ 3 = 39,964,084.3333
If the quotient is a whole number, then 3 and 39,964,084.3333 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 | 119,892,253 | |
| -1 | -119,892,253 |
Let's try dividing by 4:
119,892,253 ÷ 4 = 29,973,063.25
If the quotient is a whole number, then 4 and 29,973,063.25 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 | 119,892,253 | |
| -1 | 119,892,253 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 317 | 611 | 619 | 4,121 | 8,047 | 14,899 | 29,093 | 193,687 | 196,223 | 378,209 | 2,550,899 | 9,222,481 | 119,892,253 |
| -1 | -13 | -47 | -317 | -611 | -619 | -4,121 | -8,047 | -14,899 | -29,093 | -193,687 | -196,223 | -378,209 | -2,550,899 | -9,222,481 | -119,892,253 |
