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 100,430,105, 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 | 100,430,105 | |
| -1 | -100,430,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,430,105.
Example:
1 x 100,430,105 = 100,430,105
and
-1 x -100,430,105 = 100,430,105
Notice both answers equal 100,430,105
With that explanation out of the way, let's continue. Next, we take the number 100,430,105 and divide it by 2:
100,430,105 ÷ 2 = 50,215,052.5
If the quotient is a whole number, then 2 and 50,215,052.5 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 | 100,430,105 | |
| -1 | -100,430,105 |
Now, we try dividing 100,430,105 by 3:
100,430,105 ÷ 3 = 33,476,701.6667
If the quotient is a whole number, then 3 and 33,476,701.6667 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 | 100,430,105 | |
| -1 | -100,430,105 |
Let's try dividing by 4:
100,430,105 ÷ 4 = 25,107,526.25
If the quotient is a whole number, then 4 and 25,107,526.25 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 | 100,430,105 | |
| -1 | 100,430,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 601 | 1,759 | 3,005 | 8,795 | 11,419 | 33,421 | 57,095 | 167,105 | 1,057,159 | 5,285,795 | 20,086,021 | 100,430,105 |
| -1 | -5 | -19 | -95 | -601 | -1,759 | -3,005 | -8,795 | -11,419 | -33,421 | -57,095 | -167,105 | -1,057,159 | -5,285,795 | -20,086,021 | -100,430,105 |
