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 112,242,053, 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 | 112,242,053 | |
| -1 | -112,242,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,242,053.
Example:
1 x 112,242,053 = 112,242,053
and
-1 x -112,242,053 = 112,242,053
Notice both answers equal 112,242,053
With that explanation out of the way, let's continue. Next, we take the number 112,242,053 and divide it by 2:
112,242,053 ÷ 2 = 56,121,026.5
If the quotient is a whole number, then 2 and 56,121,026.5 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 | 112,242,053 | |
| -1 | -112,242,053 |
Now, we try dividing 112,242,053 by 3:
112,242,053 ÷ 3 = 37,414,017.6667
If the quotient is a whole number, then 3 and 37,414,017.6667 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 | 112,242,053 | |
| -1 | -112,242,053 |
Let's try dividing by 4:
112,242,053 ÷ 4 = 28,060,513.25
If the quotient is a whole number, then 4 and 28,060,513.25 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 | 112,242,053 | |
| -1 | 112,242,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 2,849 | 39,397 | 275,779 | 433,367 | 1,457,689 | 3,033,569 | 10,203,823 | 16,034,579 | 112,242,053 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -2,849 | -39,397 | -275,779 | -433,367 | -1,457,689 | -3,033,569 | -10,203,823 | -16,034,579 | -112,242,053 |
