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 356,326,625, 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 | 356,326,625 | |
| -1 | -356,326,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,326,625.
Example:
1 x 356,326,625 = 356,326,625
and
-1 x -356,326,625 = 356,326,625
Notice both answers equal 356,326,625
With that explanation out of the way, let's continue. Next, we take the number 356,326,625 and divide it by 2:
356,326,625 ÷ 2 = 178,163,312.5
If the quotient is a whole number, then 2 and 178,163,312.5 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 | 356,326,625 | |
| -1 | -356,326,625 |
Now, we try dividing 356,326,625 by 3:
356,326,625 ÷ 3 = 118,775,541.6667
If the quotient is a whole number, then 3 and 118,775,541.6667 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 | 356,326,625 | |
| -1 | -356,326,625 |
Let's try dividing by 4:
356,326,625 ÷ 4 = 89,081,656.25
If the quotient is a whole number, then 4 and 89,081,656.25 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 | 356,326,625 | |
| -1 | 356,326,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 125 | 145 | 725 | 3,625 | 98,297 | 491,485 | 2,457,425 | 2,850,613 | 12,287,125 | 14,253,065 | 71,265,325 | 356,326,625 |
| -1 | -5 | -25 | -29 | -125 | -145 | -725 | -3,625 | -98,297 | -491,485 | -2,457,425 | -2,850,613 | -12,287,125 | -14,253,065 | -71,265,325 | -356,326,625 |
