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 335,403,445, 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 | 335,403,445 | |
| -1 | -335,403,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 335,403,445.
Example:
1 x 335,403,445 = 335,403,445
and
-1 x -335,403,445 = 335,403,445
Notice both answers equal 335,403,445
With that explanation out of the way, let's continue. Next, we take the number 335,403,445 and divide it by 2:
335,403,445 ÷ 2 = 167,701,722.5
If the quotient is a whole number, then 2 and 167,701,722.5 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 | 335,403,445 | |
| -1 | -335,403,445 |
Now, we try dividing 335,403,445 by 3:
335,403,445 ÷ 3 = 111,801,148.3333
If the quotient is a whole number, then 3 and 111,801,148.3333 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 | 335,403,445 | |
| -1 | -335,403,445 |
Let's try dividing by 4:
335,403,445 ÷ 4 = 83,850,861.25
If the quotient is a whole number, then 4 and 83,850,861.25 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 | 335,403,445 | |
| -1 | 335,403,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,093 | 4,721 | 5,465 | 14,209 | 23,605 | 61,373 | 71,045 | 306,865 | 5,160,053 | 25,800,265 | 67,080,689 | 335,403,445 |
| -1 | -5 | -13 | -65 | -1,093 | -4,721 | -5,465 | -14,209 | -23,605 | -61,373 | -71,045 | -306,865 | -5,160,053 | -25,800,265 | -67,080,689 | -335,403,445 |
