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 352,250,353, 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 | 352,250,353 | |
| -1 | -352,250,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 352,250,353.
Example:
1 x 352,250,353 = 352,250,353
and
-1 x -352,250,353 = 352,250,353
Notice both answers equal 352,250,353
With that explanation out of the way, let's continue. Next, we take the number 352,250,353 and divide it by 2:
352,250,353 ÷ 2 = 176,125,176.5
If the quotient is a whole number, then 2 and 176,125,176.5 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 | 352,250,353 | |
| -1 | -352,250,353 |
Now, we try dividing 352,250,353 by 3:
352,250,353 ÷ 3 = 117,416,784.3333
If the quotient is a whole number, then 3 and 117,416,784.3333 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 | 352,250,353 | |
| -1 | -352,250,353 |
Let's try dividing by 4:
352,250,353 ÷ 4 = 88,062,588.25
If the quotient is a whole number, then 4 and 88,062,588.25 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 | 352,250,353 | |
| -1 | 352,250,353 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 227,699 | 1,593,893 | 2,960,087 | 3,870,883 | 20,720,609 | 27,096,181 | 50,321,479 | 352,250,353 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -227,699 | -1,593,893 | -2,960,087 | -3,870,883 | -20,720,609 | -27,096,181 | -50,321,479 | -352,250,353 |
