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 352,235,851, 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 | 352,235,851 | |
| -1 | -352,235,851 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,235,851.
Example:
1 x 352,235,851 = 352,235,851
and
-1 x -352,235,851 = 352,235,851
Notice both answers equal 352,235,851
With that explanation out of the way, let's continue. Next, we take the number 352,235,851 and divide it by 2:
352,235,851 ÷ 2 = 176,117,925.5
If the quotient is a whole number, then 2 and 176,117,925.5 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 | 352,235,851 | |
| -1 | -352,235,851 |
Now, we try dividing 352,235,851 by 3:
352,235,851 ÷ 3 = 117,411,950.3333
If the quotient is a whole number, then 3 and 117,411,950.3333 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 | 352,235,851 | |
| -1 | -352,235,851 |
Let's try dividing by 4:
352,235,851 ÷ 4 = 88,058,962.75
If the quotient is a whole number, then 4 and 88,058,962.75 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 | 352,235,851 | |
| -1 | 352,235,851 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 149 | 209 | 1,639 | 2,831 | 11,311 | 31,141 | 124,421 | 214,909 | 1,685,339 | 2,363,999 | 18,538,729 | 32,021,441 | 352,235,851 |
| -1 | -11 | -19 | -149 | -209 | -1,639 | -2,831 | -11,311 | -31,141 | -124,421 | -214,909 | -1,685,339 | -2,363,999 | -18,538,729 | -32,021,441 | -352,235,851 |
