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 354,507,103, 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 | 354,507,103 | |
| -1 | -354,507,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 354,507,103.
Example:
1 x 354,507,103 = 354,507,103
and
-1 x -354,507,103 = 354,507,103
Notice both answers equal 354,507,103
With that explanation out of the way, let's continue. Next, we take the number 354,507,103 and divide it by 2:
354,507,103 ÷ 2 = 177,253,551.5
If the quotient is a whole number, then 2 and 177,253,551.5 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 | 354,507,103 | |
| -1 | -354,507,103 |
Now, we try dividing 354,507,103 by 3:
354,507,103 ÷ 3 = 118,169,034.3333
If the quotient is a whole number, then 3 and 118,169,034.3333 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 | 354,507,103 | |
| -1 | -354,507,103 |
Let's try dividing by 4:
354,507,103 ÷ 4 = 88,626,775.75
If the quotient is a whole number, then 4 and 88,626,775.75 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 | 354,507,103 | |
| -1 | 354,507,103 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 113 | 527 | 1,921 | 3,503 | 5,953 | 59,551 | 101,201 | 184,543 | 672,689 | 3,137,231 | 11,435,713 | 20,853,359 | 354,507,103 |
| -1 | -17 | -31 | -113 | -527 | -1,921 | -3,503 | -5,953 | -59,551 | -101,201 | -184,543 | -672,689 | -3,137,231 | -11,435,713 | -20,853,359 | -354,507,103 |
