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 440,006,455, 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 | 440,006,455 | |
| -1 | -440,006,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,006,455.
Example:
1 x 440,006,455 = 440,006,455
and
-1 x -440,006,455 = 440,006,455
Notice both answers equal 440,006,455
With that explanation out of the way, let's continue. Next, we take the number 440,006,455 and divide it by 2:
440,006,455 ÷ 2 = 220,003,227.5
If the quotient is a whole number, then 2 and 220,003,227.5 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 | 440,006,455 | |
| -1 | -440,006,455 |
Now, we try dividing 440,006,455 by 3:
440,006,455 ÷ 3 = 146,668,818.3333
If the quotient is a whole number, then 3 and 146,668,818.3333 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 | 440,006,455 | |
| -1 | -440,006,455 |
Let's try dividing by 4:
440,006,455 ÷ 4 = 110,001,613.75
If the quotient is a whole number, then 4 and 110,001,613.75 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 | 440,006,455 | |
| -1 | 440,006,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 2,285 | 3,199 | 15,995 | 27,509 | 137,545 | 192,563 | 962,815 | 12,571,613 | 62,858,065 | 88,001,291 | 440,006,455 |
| -1 | -5 | -7 | -35 | -457 | -2,285 | -3,199 | -15,995 | -27,509 | -137,545 | -192,563 | -962,815 | -12,571,613 | -62,858,065 | -88,001,291 | -440,006,455 |
