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 356,541,451, 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 | 356,541,451 | |
| -1 | -356,541,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,541,451.
Example:
1 x 356,541,451 = 356,541,451
and
-1 x -356,541,451 = 356,541,451
Notice both answers equal 356,541,451
With that explanation out of the way, let's continue. Next, we take the number 356,541,451 and divide it by 2:
356,541,451 ÷ 2 = 178,270,725.5
If the quotient is a whole number, then 2 and 178,270,725.5 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 | 356,541,451 | |
| -1 | -356,541,451 |
Now, we try dividing 356,541,451 by 3:
356,541,451 ÷ 3 = 118,847,150.3333
If the quotient is a whole number, then 3 and 118,847,150.3333 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 | 356,541,451 | |
| -1 | -356,541,451 |
Let's try dividing by 4:
356,541,451 ÷ 4 = 89,135,362.75
If the quotient is a whole number, then 4 and 89,135,362.75 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 | 356,541,451 | |
| -1 | 356,541,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 127 | 389 | 889 | 1,031 | 2,723 | 7,217 | 49,403 | 130,937 | 345,821 | 401,059 | 916,559 | 2,807,413 | 50,934,493 | 356,541,451 |
| -1 | -7 | -127 | -389 | -889 | -1,031 | -2,723 | -7,217 | -49,403 | -130,937 | -345,821 | -401,059 | -916,559 | -2,807,413 | -50,934,493 | -356,541,451 |
