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 423,154,111, 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 | 423,154,111 | |
| -1 | -423,154,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 423,154,111.
Example:
1 x 423,154,111 = 423,154,111
and
-1 x -423,154,111 = 423,154,111
Notice both answers equal 423,154,111
With that explanation out of the way, let's continue. Next, we take the number 423,154,111 and divide it by 2:
423,154,111 ÷ 2 = 211,577,055.5
If the quotient is a whole number, then 2 and 211,577,055.5 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 | 423,154,111 | |
| -1 | -423,154,111 |
Now, we try dividing 423,154,111 by 3:
423,154,111 ÷ 3 = 141,051,370.3333
If the quotient is a whole number, then 3 and 141,051,370.3333 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 | 423,154,111 | |
| -1 | -423,154,111 |
Let's try dividing by 4:
423,154,111 ÷ 4 = 105,788,527.75
If the quotient is a whole number, then 4 and 105,788,527.75 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 | 423,154,111 | |
| -1 | 423,154,111 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 491 | 677 | 1,273 | 9,329 | 12,863 | 32,897 | 45,359 | 332,407 | 625,043 | 861,821 | 6,315,733 | 22,271,269 | 423,154,111 |
| -1 | -19 | -67 | -491 | -677 | -1,273 | -9,329 | -12,863 | -32,897 | -45,359 | -332,407 | -625,043 | -861,821 | -6,315,733 | -22,271,269 | -423,154,111 |
