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 359,160,785, 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 | 359,160,785 | |
| -1 | -359,160,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 359,160,785.
Example:
1 x 359,160,785 = 359,160,785
and
-1 x -359,160,785 = 359,160,785
Notice both answers equal 359,160,785
With that explanation out of the way, let's continue. Next, we take the number 359,160,785 and divide it by 2:
359,160,785 ÷ 2 = 179,580,392.5
If the quotient is a whole number, then 2 and 179,580,392.5 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 | 359,160,785 | |
| -1 | -359,160,785 |
Now, we try dividing 359,160,785 by 3:
359,160,785 ÷ 3 = 119,720,261.6667
If the quotient is a whole number, then 3 and 119,720,261.6667 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 | 359,160,785 | |
| -1 | -359,160,785 |
Let's try dividing by 4:
359,160,785 ÷ 4 = 89,790,196.25
If the quotient is a whole number, then 4 and 89,790,196.25 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 | 359,160,785 | |
| -1 | 359,160,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 859 | 4,295 | 4,919 | 14,603 | 24,595 | 73,015 | 83,623 | 418,115 | 4,225,421 | 21,127,105 | 71,832,157 | 359,160,785 |
| -1 | -5 | -17 | -85 | -859 | -4,295 | -4,919 | -14,603 | -24,595 | -73,015 | -83,623 | -418,115 | -4,225,421 | -21,127,105 | -71,832,157 | -359,160,785 |
