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 340,455,535, 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 | 340,455,535 | |
| -1 | -340,455,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,455,535.
Example:
1 x 340,455,535 = 340,455,535
and
-1 x -340,455,535 = 340,455,535
Notice both answers equal 340,455,535
With that explanation out of the way, let's continue. Next, we take the number 340,455,535 and divide it by 2:
340,455,535 ÷ 2 = 170,227,767.5
If the quotient is a whole number, then 2 and 170,227,767.5 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 | 340,455,535 | |
| -1 | -340,455,535 |
Now, we try dividing 340,455,535 by 3:
340,455,535 ÷ 3 = 113,485,178.3333
If the quotient is a whole number, then 3 and 113,485,178.3333 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 | 340,455,535 | |
| -1 | -340,455,535 |
Let's try dividing by 4:
340,455,535 ÷ 4 = 85,113,883.75
If the quotient is a whole number, then 4 and 85,113,883.75 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 | 340,455,535 | |
| -1 | 340,455,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 547 | 2,735 | 3,829 | 17,783 | 19,145 | 88,915 | 124,481 | 622,405 | 9,727,301 | 48,636,505 | 68,091,107 | 340,455,535 |
| -1 | -5 | -7 | -35 | -547 | -2,735 | -3,829 | -17,783 | -19,145 | -88,915 | -124,481 | -622,405 | -9,727,301 | -48,636,505 | -68,091,107 | -340,455,535 |
