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 112,242,445, 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 | 112,242,445 | |
| -1 | -112,242,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,242,445.
Example:
1 x 112,242,445 = 112,242,445
and
-1 x -112,242,445 = 112,242,445
Notice both answers equal 112,242,445
With that explanation out of the way, let's continue. Next, we take the number 112,242,445 and divide it by 2:
112,242,445 ÷ 2 = 56,121,222.5
If the quotient is a whole number, then 2 and 56,121,222.5 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 | 112,242,445 | |
| -1 | -112,242,445 |
Now, we try dividing 112,242,445 by 3:
112,242,445 ÷ 3 = 37,414,148.3333
If the quotient is a whole number, then 3 and 37,414,148.3333 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 | 112,242,445 | |
| -1 | -112,242,445 |
Let's try dividing by 4:
112,242,445 ÷ 4 = 28,060,611.25
If the quotient is a whole number, then 4 and 28,060,611.25 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 | 112,242,445 | |
| -1 | 112,242,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 149 | 745 | 1,043 | 5,215 | 21,523 | 107,615 | 150,661 | 753,305 | 3,206,927 | 16,034,635 | 22,448,489 | 112,242,445 |
| -1 | -5 | -7 | -35 | -149 | -745 | -1,043 | -5,215 | -21,523 | -107,615 | -150,661 | -753,305 | -3,206,927 | -16,034,635 | -22,448,489 | -112,242,445 |
