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 100,804,237, 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 | 100,804,237 | |
| -1 | -100,804,237 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,804,237.
Example:
1 x 100,804,237 = 100,804,237
and
-1 x -100,804,237 = 100,804,237
Notice both answers equal 100,804,237
With that explanation out of the way, let's continue. Next, we take the number 100,804,237 and divide it by 2:
100,804,237 ÷ 2 = 50,402,118.5
If the quotient is a whole number, then 2 and 50,402,118.5 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 | 100,804,237 | |
| -1 | -100,804,237 |
Now, we try dividing 100,804,237 by 3:
100,804,237 ÷ 3 = 33,601,412.3333
If the quotient is a whole number, then 3 and 33,601,412.3333 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 | 100,804,237 | |
| -1 | -100,804,237 |
Let's try dividing by 4:
100,804,237 ÷ 4 = 25,201,059.25
If the quotient is a whole number, then 4 and 25,201,059.25 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 | 100,804,237 | |
| -1 | 100,804,237 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 79 | 799 | 1,343 | 1,597 | 3,713 | 27,149 | 63,121 | 75,059 | 126,163 | 1,276,003 | 2,144,771 | 5,929,661 | 100,804,237 |
| -1 | -17 | -47 | -79 | -799 | -1,343 | -1,597 | -3,713 | -27,149 | -63,121 | -75,059 | -126,163 | -1,276,003 | -2,144,771 | -5,929,661 | -100,804,237 |
