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 440,352,257, 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 | 440,352,257 | |
-1 | -440,352,257 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,352,257.
Example:
1 x 440,352,257 = 440,352,257
and
-1 x -440,352,257 = 440,352,257
Notice both answers equal 440,352,257
With that explanation out of the way, let's continue. Next, we take the number 440,352,257 and divide it by 2:
440,352,257 ÷ 2 = 220,176,128.5
If the quotient is a whole number, then 2 and 220,176,128.5 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 | 440,352,257 | |
-1 | -440,352,257 |
Now, we try dividing 440,352,257 by 3:
440,352,257 ÷ 3 = 146,784,085.6667
If the quotient is a whole number, then 3 and 146,784,085.6667 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 | 440,352,257 | |
-1 | -440,352,257 |
Let's try dividing by 4:
440,352,257 ÷ 4 = 110,088,064.25
If the quotient is a whole number, then 4 and 110,088,064.25 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 | 440,352,257 | |
-1 | 440,352,257 |
If you did it right, you will end up with this table:
1 | 641 | 686,977 | 440,352,257 |
-1 | -641 | -686,977 | -440,352,257 |
