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 100,340,669, 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 | 100,340,669 | |
| -1 | -100,340,669 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,340,669.
Example:
1 x 100,340,669 = 100,340,669
and
-1 x -100,340,669 = 100,340,669
Notice both answers equal 100,340,669
With that explanation out of the way, let's continue. Next, we take the number 100,340,669 and divide it by 2:
100,340,669 ÷ 2 = 50,170,334.5
If the quotient is a whole number, then 2 and 50,170,334.5 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 | 100,340,669 | |
| -1 | -100,340,669 |
Now, we try dividing 100,340,669 by 3:
100,340,669 ÷ 3 = 33,446,889.6667
If the quotient is a whole number, then 3 and 33,446,889.6667 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 | 100,340,669 | |
| -1 | -100,340,669 |
Let's try dividing by 4:
100,340,669 ÷ 4 = 25,085,167.25
If the quotient is a whole number, then 4 and 25,085,167.25 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 | 100,340,669 | |
| -1 | 100,340,669 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 61 | 143 | 671 | 793 | 8,723 | 11,503 | 126,533 | 149,539 | 701,683 | 1,644,929 | 7,718,513 | 9,121,879 | 100,340,669 |
| -1 | -11 | -13 | -61 | -143 | -671 | -793 | -8,723 | -11,503 | -126,533 | -149,539 | -701,683 | -1,644,929 | -7,718,513 | -9,121,879 | -100,340,669 |
