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 352,254,145, 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 | 352,254,145 | |
| -1 | -352,254,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,254,145.
Example:
1 x 352,254,145 = 352,254,145
and
-1 x -352,254,145 = 352,254,145
Notice both answers equal 352,254,145
With that explanation out of the way, let's continue. Next, we take the number 352,254,145 and divide it by 2:
352,254,145 ÷ 2 = 176,127,072.5
If the quotient is a whole number, then 2 and 176,127,072.5 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 | 352,254,145 | |
| -1 | -352,254,145 |
Now, we try dividing 352,254,145 by 3:
352,254,145 ÷ 3 = 117,418,048.3333
If the quotient is a whole number, then 3 and 117,418,048.3333 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 | 352,254,145 | |
| -1 | -352,254,145 |
Let's try dividing by 4:
352,254,145 ÷ 4 = 88,063,536.25
If the quotient is a whole number, then 4 and 88,063,536.25 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 | 352,254,145 | |
| -1 | 352,254,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 223 | 431 | 733 | 1,115 | 2,155 | 3,665 | 96,113 | 163,459 | 315,923 | 480,565 | 817,295 | 1,579,615 | 70,450,829 | 352,254,145 |
| -1 | -5 | -223 | -431 | -733 | -1,115 | -2,155 | -3,665 | -96,113 | -163,459 | -315,923 | -480,565 | -817,295 | -1,579,615 | -70,450,829 | -352,254,145 |
