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 100,351,445, 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 | 100,351,445 | |
| -1 | -100,351,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,351,445.
Example:
1 x 100,351,445 = 100,351,445
and
-1 x -100,351,445 = 100,351,445
Notice both answers equal 100,351,445
With that explanation out of the way, let's continue. Next, we take the number 100,351,445 and divide it by 2:
100,351,445 ÷ 2 = 50,175,722.5
If the quotient is a whole number, then 2 and 50,175,722.5 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 | 100,351,445 | |
| -1 | -100,351,445 |
Now, we try dividing 100,351,445 by 3:
100,351,445 ÷ 3 = 33,450,481.6667
If the quotient is a whole number, then 3 and 33,450,481.6667 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 | 100,351,445 | |
| -1 | -100,351,445 |
Let's try dividing by 4:
100,351,445 ÷ 4 = 25,087,861.25
If the quotient is a whole number, then 4 and 25,087,861.25 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 | 100,351,445 | |
| -1 | 100,351,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 727 | 1,453 | 3,635 | 7,265 | 13,813 | 27,607 | 69,065 | 138,035 | 1,056,331 | 5,281,655 | 20,070,289 | 100,351,445 |
| -1 | -5 | -19 | -95 | -727 | -1,453 | -3,635 | -7,265 | -13,813 | -27,607 | -69,065 | -138,035 | -1,056,331 | -5,281,655 | -20,070,289 | -100,351,445 |
