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 351,253,019, 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 | 351,253,019 | |
| -1 | -351,253,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,253,019.
Example:
1 x 351,253,019 = 351,253,019
and
-1 x -351,253,019 = 351,253,019
Notice both answers equal 351,253,019
With that explanation out of the way, let's continue. Next, we take the number 351,253,019 and divide it by 2:
351,253,019 ÷ 2 = 175,626,509.5
If the quotient is a whole number, then 2 and 175,626,509.5 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 | 351,253,019 | |
| -1 | -351,253,019 |
Now, we try dividing 351,253,019 by 3:
351,253,019 ÷ 3 = 117,084,339.6667
If the quotient is a whole number, then 3 and 117,084,339.6667 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 | 351,253,019 | |
| -1 | -351,253,019 |
Let's try dividing by 4:
351,253,019 ÷ 4 = 87,813,254.75
If the quotient is a whole number, then 4 and 87,813,254.75 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 | 351,253,019 | |
| -1 | 351,253,019 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 59 | 247 | 767 | 1,121 | 14,573 | 24,103 | 313,339 | 457,957 | 1,422,077 | 5,953,441 | 18,487,001 | 27,019,463 | 351,253,019 |
| -1 | -13 | -19 | -59 | -247 | -767 | -1,121 | -14,573 | -24,103 | -313,339 | -457,957 | -1,422,077 | -5,953,441 | -18,487,001 | -27,019,463 | -351,253,019 |
