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 445,512,035, 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 | 445,512,035 | |
| -1 | -445,512,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 445,512,035.
Example:
1 x 445,512,035 = 445,512,035
and
-1 x -445,512,035 = 445,512,035
Notice both answers equal 445,512,035
With that explanation out of the way, let's continue. Next, we take the number 445,512,035 and divide it by 2:
445,512,035 ÷ 2 = 222,756,017.5
If the quotient is a whole number, then 2 and 222,756,017.5 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 | 445,512,035 | |
| -1 | -445,512,035 |
Now, we try dividing 445,512,035 by 3:
445,512,035 ÷ 3 = 148,504,011.6667
If the quotient is a whole number, then 3 and 148,504,011.6667 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 | 445,512,035 | |
| -1 | -445,512,035 |
Let's try dividing by 4:
445,512,035 ÷ 4 = 111,378,008.75
If the quotient is a whole number, then 4 and 111,378,008.75 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 | 445,512,035 | |
| -1 | 445,512,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 1,319 | 1,571 | 6,595 | 7,855 | 56,717 | 67,553 | 283,585 | 337,765 | 2,072,149 | 10,360,745 | 89,102,407 | 445,512,035 |
| -1 | -5 | -43 | -215 | -1,319 | -1,571 | -6,595 | -7,855 | -56,717 | -67,553 | -283,585 | -337,765 | -2,072,149 | -10,360,745 | -89,102,407 | -445,512,035 |
