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 355,425,505, 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 | 355,425,505 | |
| -1 | -355,425,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,425,505.
Example:
1 x 355,425,505 = 355,425,505
and
-1 x -355,425,505 = 355,425,505
Notice both answers equal 355,425,505
With that explanation out of the way, let's continue. Next, we take the number 355,425,505 and divide it by 2:
355,425,505 ÷ 2 = 177,712,752.5
If the quotient is a whole number, then 2 and 177,712,752.5 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 | 355,425,505 | |
| -1 | -355,425,505 |
Now, we try dividing 355,425,505 by 3:
355,425,505 ÷ 3 = 118,475,168.3333
If the quotient is a whole number, then 3 and 118,475,168.3333 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 | 355,425,505 | |
| -1 | -355,425,505 |
Let's try dividing by 4:
355,425,505 ÷ 4 = 88,856,376.25
If the quotient is a whole number, then 4 and 88,856,376.25 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 | 355,425,505 | |
| -1 | 355,425,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 89 | 415 | 445 | 7,387 | 9,623 | 36,935 | 48,115 | 798,709 | 856,447 | 3,993,545 | 4,282,235 | 71,085,101 | 355,425,505 |
| -1 | -5 | -83 | -89 | -415 | -445 | -7,387 | -9,623 | -36,935 | -48,115 | -798,709 | -856,447 | -3,993,545 | -4,282,235 | -71,085,101 | -355,425,505 |
