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 112,235,641, 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 | 112,235,641 | |
| -1 | -112,235,641 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,235,641.
Example:
1 x 112,235,641 = 112,235,641
and
-1 x -112,235,641 = 112,235,641
Notice both answers equal 112,235,641
With that explanation out of the way, let's continue. Next, we take the number 112,235,641 and divide it by 2:
112,235,641 ÷ 2 = 56,117,820.5
If the quotient is a whole number, then 2 and 56,117,820.5 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 | 112,235,641 | |
| -1 | -112,235,641 |
Now, we try dividing 112,235,641 by 3:
112,235,641 ÷ 3 = 37,411,880.3333
If the quotient is a whole number, then 3 and 37,411,880.3333 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 | 112,235,641 | |
| -1 | -112,235,641 |
Let's try dividing by 4:
112,235,641 ÷ 4 = 28,058,910.25
If the quotient is a whole number, then 4 and 28,058,910.25 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 | 112,235,641 | |
| -1 | 112,235,641 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 59 | 133 | 413 | 1,121 | 7,847 | 14,303 | 100,121 | 271,757 | 843,877 | 1,902,299 | 5,907,139 | 16,033,663 | 112,235,641 |
| -1 | -7 | -19 | -59 | -133 | -413 | -1,121 | -7,847 | -14,303 | -100,121 | -271,757 | -843,877 | -1,902,299 | -5,907,139 | -16,033,663 | -112,235,641 |
