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 440,135,423, 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 | 440,135,423 | |
| -1 | -440,135,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,135,423.
Example:
1 x 440,135,423 = 440,135,423
and
-1 x -440,135,423 = 440,135,423
Notice both answers equal 440,135,423
With that explanation out of the way, let's continue. Next, we take the number 440,135,423 and divide it by 2:
440,135,423 ÷ 2 = 220,067,711.5
If the quotient is a whole number, then 2 and 220,067,711.5 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 | 440,135,423 | |
| -1 | -440,135,423 |
Now, we try dividing 440,135,423 by 3:
440,135,423 ÷ 3 = 146,711,807.6667
If the quotient is a whole number, then 3 and 146,711,807.6667 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 | 440,135,423 | |
| -1 | -440,135,423 |
Let's try dividing by 4:
440,135,423 ÷ 4 = 110,033,855.75
If the quotient is a whole number, then 4 and 110,033,855.75 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 | 440,135,423 | |
| -1 | 440,135,423 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 284,509 | 1,991,563 | 3,698,617 | 4,836,653 | 25,890,319 | 33,856,571 | 62,876,489 | 440,135,423 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -284,509 | -1,991,563 | -3,698,617 | -4,836,653 | -25,890,319 | -33,856,571 | -62,876,489 | -440,135,423 |
