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 350,634,311, 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 | 350,634,311 | |
| -1 | -350,634,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 350,634,311.
Example:
1 x 350,634,311 = 350,634,311
and
-1 x -350,634,311 = 350,634,311
Notice both answers equal 350,634,311
With that explanation out of the way, let's continue. Next, we take the number 350,634,311 and divide it by 2:
350,634,311 ÷ 2 = 175,317,155.5
If the quotient is a whole number, then 2 and 175,317,155.5 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 | 350,634,311 | |
| -1 | -350,634,311 |
Now, we try dividing 350,634,311 by 3:
350,634,311 ÷ 3 = 116,878,103.6667
If the quotient is a whole number, then 3 and 116,878,103.6667 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 | 350,634,311 | |
| -1 | -350,634,311 |
Let's try dividing by 4:
350,634,311 ÷ 4 = 87,658,577.75
If the quotient is a whole number, then 4 and 87,658,577.75 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 | 350,634,311 | |
| -1 | 350,634,311 |
If you did it right, you will end up with this table:
| 1 | 37 | 79 | 139 | 863 | 2,923 | 5,143 | 10,981 | 31,931 | 68,177 | 119,957 | 406,297 | 2,522,549 | 4,438,409 | 9,476,603 | 350,634,311 |
| -1 | -37 | -79 | -139 | -863 | -2,923 | -5,143 | -10,981 | -31,931 | -68,177 | -119,957 | -406,297 | -2,522,549 | -4,438,409 | -9,476,603 | -350,634,311 |
