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 112,103,453, 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 | 112,103,453 | |
| -1 | -112,103,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,103,453.
Example:
1 x 112,103,453 = 112,103,453
and
-1 x -112,103,453 = 112,103,453
Notice both answers equal 112,103,453
With that explanation out of the way, let's continue. Next, we take the number 112,103,453 and divide it by 2:
112,103,453 ÷ 2 = 56,051,726.5
If the quotient is a whole number, then 2 and 56,051,726.5 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 | 112,103,453 | |
| -1 | -112,103,453 |
Now, we try dividing 112,103,453 by 3:
112,103,453 ÷ 3 = 37,367,817.6667
If the quotient is a whole number, then 3 and 37,367,817.6667 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 | 112,103,453 | |
| -1 | -112,103,453 |
Let's try dividing by 4:
112,103,453 ÷ 4 = 28,025,863.25
If the quotient is a whole number, then 4 and 28,025,863.25 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 | 112,103,453 | |
| -1 | 112,103,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 367 | 2,569 | 3,967 | 4,037 | 27,769 | 28,259 | 43,637 | 305,459 | 1,455,889 | 10,191,223 | 16,014,779 | 112,103,453 |
| -1 | -7 | -11 | -77 | -367 | -2,569 | -3,967 | -4,037 | -27,769 | -28,259 | -43,637 | -305,459 | -1,455,889 | -10,191,223 | -16,014,779 | -112,103,453 |
