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 446,243,305, 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 | 446,243,305 | |
| -1 | -446,243,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 446,243,305.
Example:
1 x 446,243,305 = 446,243,305
and
-1 x -446,243,305 = 446,243,305
Notice both answers equal 446,243,305
With that explanation out of the way, let's continue. Next, we take the number 446,243,305 and divide it by 2:
446,243,305 ÷ 2 = 223,121,652.5
If the quotient is a whole number, then 2 and 223,121,652.5 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 | 446,243,305 | |
| -1 | -446,243,305 |
Now, we try dividing 446,243,305 by 3:
446,243,305 ÷ 3 = 148,747,768.3333
If the quotient is a whole number, then 3 and 148,747,768.3333 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 | 446,243,305 | |
| -1 | -446,243,305 |
Let's try dividing by 4:
446,243,305 ÷ 4 = 111,560,826.25
If the quotient is a whole number, then 4 and 111,560,826.25 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 | 446,243,305 | |
| -1 | 446,243,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 433 | 2,165 | 3,889 | 19,445 | 22,949 | 114,745 | 206,117 | 1,030,585 | 1,683,937 | 8,419,685 | 89,248,661 | 446,243,305 |
| -1 | -5 | -53 | -265 | -433 | -2,165 | -3,889 | -19,445 | -22,949 | -114,745 | -206,117 | -1,030,585 | -1,683,937 | -8,419,685 | -89,248,661 | -446,243,305 |
