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 423,272,773, 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 | 423,272,773 | |
| -1 | -423,272,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 423,272,773.
Example:
1 x 423,272,773 = 423,272,773
and
-1 x -423,272,773 = 423,272,773
Notice both answers equal 423,272,773
With that explanation out of the way, let's continue. Next, we take the number 423,272,773 and divide it by 2:
423,272,773 ÷ 2 = 211,636,386.5
If the quotient is a whole number, then 2 and 211,636,386.5 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 | 423,272,773 | |
| -1 | -423,272,773 |
Now, we try dividing 423,272,773 by 3:
423,272,773 ÷ 3 = 141,090,924.3333
If the quotient is a whole number, then 3 and 141,090,924.3333 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 | 423,272,773 | |
| -1 | -423,272,773 |
Let's try dividing by 4:
423,272,773 ÷ 4 = 105,818,193.25
If the quotient is a whole number, then 4 and 105,818,193.25 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 | 423,272,773 | |
| -1 | 423,272,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,423 | 3,863 | 9,961 | 15,653 | 27,041 | 42,493 | 109,571 | 297,451 | 5,497,049 | 38,479,343 | 60,467,539 | 423,272,773 |
| -1 | -7 | -11 | -77 | -1,423 | -3,863 | -9,961 | -15,653 | -27,041 | -42,493 | -109,571 | -297,451 | -5,497,049 | -38,479,343 | -60,467,539 | -423,272,773 |
