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 100,430,203, 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 | 100,430,203 | |
| -1 | -100,430,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,430,203.
Example:
1 x 100,430,203 = 100,430,203
and
-1 x -100,430,203 = 100,430,203
Notice both answers equal 100,430,203
With that explanation out of the way, let's continue. Next, we take the number 100,430,203 and divide it by 2:
100,430,203 ÷ 2 = 50,215,101.5
If the quotient is a whole number, then 2 and 50,215,101.5 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 | 100,430,203 | |
| -1 | -100,430,203 |
Now, we try dividing 100,430,203 by 3:
100,430,203 ÷ 3 = 33,476,734.3333
If the quotient is a whole number, then 3 and 33,476,734.3333 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 | 100,430,203 | |
| -1 | -100,430,203 |
Let's try dividing by 4:
100,430,203 ÷ 4 = 25,107,550.75
If the quotient is a whole number, then 4 and 25,107,550.75 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 | 100,430,203 | |
| -1 | 100,430,203 |
If you did it right, you will end up with this table:
| 1 | 17 | 127 | 181 | 257 | 2,159 | 3,077 | 4,369 | 22,987 | 32,639 | 46,517 | 390,779 | 554,863 | 790,789 | 5,907,659 | 100,430,203 |
| -1 | -17 | -127 | -181 | -257 | -2,159 | -3,077 | -4,369 | -22,987 | -32,639 | -46,517 | -390,779 | -554,863 | -790,789 | -5,907,659 | -100,430,203 |
