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 112,003,445, 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 | 112,003,445 | |
| -1 | -112,003,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,003,445.
Example:
1 x 112,003,445 = 112,003,445
and
-1 x -112,003,445 = 112,003,445
Notice both answers equal 112,003,445
With that explanation out of the way, let's continue. Next, we take the number 112,003,445 and divide it by 2:
112,003,445 ÷ 2 = 56,001,722.5
If the quotient is a whole number, then 2 and 56,001,722.5 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 | 112,003,445 | |
| -1 | -112,003,445 |
Now, we try dividing 112,003,445 by 3:
112,003,445 ÷ 3 = 37,334,481.6667
If the quotient is a whole number, then 3 and 37,334,481.6667 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 | 112,003,445 | |
| -1 | -112,003,445 |
Let's try dividing by 4:
112,003,445 ÷ 4 = 28,000,861.25
If the quotient is a whole number, then 4 and 28,000,861.25 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 | 112,003,445 | |
| -1 | 112,003,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 101 | 115 | 505 | 2,323 | 9,643 | 11,615 | 48,215 | 221,789 | 973,943 | 1,108,945 | 4,869,715 | 22,400,689 | 112,003,445 |
| -1 | -5 | -23 | -101 | -115 | -505 | -2,323 | -9,643 | -11,615 | -48,215 | -221,789 | -973,943 | -1,108,945 | -4,869,715 | -22,400,689 | -112,003,445 |
