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 111,601,451, 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 | 111,601,451 | |
| -1 | -111,601,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,601,451.
Example:
1 x 111,601,451 = 111,601,451
and
-1 x -111,601,451 = 111,601,451
Notice both answers equal 111,601,451
With that explanation out of the way, let's continue. Next, we take the number 111,601,451 and divide it by 2:
111,601,451 ÷ 2 = 55,800,725.5
If the quotient is a whole number, then 2 and 55,800,725.5 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 | 111,601,451 | |
| -1 | -111,601,451 |
Now, we try dividing 111,601,451 by 3:
111,601,451 ÷ 3 = 37,200,483.6667
If the quotient is a whole number, then 3 and 37,200,483.6667 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 | 111,601,451 | |
| -1 | -111,601,451 |
Let's try dividing by 4:
111,601,451 ÷ 4 = 27,900,362.75
If the quotient is a whole number, then 4 and 27,900,362.75 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 | 111,601,451 | |
| -1 | 111,601,451 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 73 | 299 | 949 | 1,679 | 5,113 | 21,827 | 66,469 | 117,599 | 373,249 | 1,528,787 | 4,852,237 | 8,584,727 | 111,601,451 |
| -1 | -13 | -23 | -73 | -299 | -949 | -1,679 | -5,113 | -21,827 | -66,469 | -117,599 | -373,249 | -1,528,787 | -4,852,237 | -8,584,727 | -111,601,451 |
