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 435,110,621, 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 | 435,110,621 | |
| -1 | -435,110,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 435,110,621.
Example:
1 x 435,110,621 = 435,110,621
and
-1 x -435,110,621 = 435,110,621
Notice both answers equal 435,110,621
With that explanation out of the way, let's continue. Next, we take the number 435,110,621 and divide it by 2:
435,110,621 ÷ 2 = 217,555,310.5
If the quotient is a whole number, then 2 and 217,555,310.5 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 | 435,110,621 | |
| -1 | -435,110,621 |
Now, we try dividing 435,110,621 by 3:
435,110,621 ÷ 3 = 145,036,873.6667
If the quotient is a whole number, then 3 and 145,036,873.6667 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 | 435,110,621 | |
| -1 | -435,110,621 |
Let's try dividing by 4:
435,110,621 ÷ 4 = 108,777,655.25
If the quotient is a whole number, then 4 and 108,777,655.25 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 | 435,110,621 | |
| -1 | 435,110,621 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 61 | 209 | 671 | 1,159 | 12,749 | 34,129 | 375,419 | 648,451 | 2,081,869 | 7,132,961 | 22,900,559 | 39,555,511 | 435,110,621 |
| -1 | -11 | -19 | -61 | -209 | -671 | -1,159 | -12,749 | -34,129 | -375,419 | -648,451 | -2,081,869 | -7,132,961 | -22,900,559 | -39,555,511 | -435,110,621 |
