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 112,000,421, 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 | 112,000,421 | |
| -1 | -112,000,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,000,421.
Example:
1 x 112,000,421 = 112,000,421
and
-1 x -112,000,421 = 112,000,421
Notice both answers equal 112,000,421
With that explanation out of the way, let's continue. Next, we take the number 112,000,421 and divide it by 2:
112,000,421 ÷ 2 = 56,000,210.5
If the quotient is a whole number, then 2 and 56,000,210.5 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 | 112,000,421 | |
| -1 | -112,000,421 |
Now, we try dividing 112,000,421 by 3:
112,000,421 ÷ 3 = 37,333,473.6667
If the quotient is a whole number, then 3 and 37,333,473.6667 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 | 112,000,421 | |
| -1 | -112,000,421 |
Let's try dividing by 4:
112,000,421 ÷ 4 = 28,000,105.25
If the quotient is a whole number, then 4 and 28,000,105.25 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 | 112,000,421 | |
| -1 | 112,000,421 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 599 | 757 | 7,787 | 9,841 | 11,381 | 14,383 | 147,953 | 186,979 | 453,443 | 5,894,759 | 8,615,417 | 112,000,421 |
| -1 | -13 | -19 | -247 | -599 | -757 | -7,787 | -9,841 | -11,381 | -14,383 | -147,953 | -186,979 | -453,443 | -5,894,759 | -8,615,417 | -112,000,421 |
