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 356,527,715, 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 | 356,527,715 | |
| -1 | -356,527,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,527,715.
Example:
1 x 356,527,715 = 356,527,715
and
-1 x -356,527,715 = 356,527,715
Notice both answers equal 356,527,715
With that explanation out of the way, let's continue. Next, we take the number 356,527,715 and divide it by 2:
356,527,715 ÷ 2 = 178,263,857.5
If the quotient is a whole number, then 2 and 178,263,857.5 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 | 356,527,715 | |
| -1 | -356,527,715 |
Now, we try dividing 356,527,715 by 3:
356,527,715 ÷ 3 = 118,842,571.6667
If the quotient is a whole number, then 3 and 118,842,571.6667 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 | 356,527,715 | |
| -1 | -356,527,715 |
Let's try dividing by 4:
356,527,715 ÷ 4 = 89,131,928.75
If the quotient is a whole number, then 4 and 89,131,928.75 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 | 356,527,715 | |
| -1 | 356,527,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 823 | 3,767 | 4,115 | 18,835 | 18,929 | 86,641 | 94,645 | 433,205 | 3,100,241 | 15,501,205 | 71,305,543 | 356,527,715 |
| -1 | -5 | -23 | -115 | -823 | -3,767 | -4,115 | -18,835 | -18,929 | -86,641 | -94,645 | -433,205 | -3,100,241 | -15,501,205 | -71,305,543 | -356,527,715 |
