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 350,256,887, 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 | 350,256,887 | |
| -1 | -350,256,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 350,256,887.
Example:
1 x 350,256,887 = 350,256,887
and
-1 x -350,256,887 = 350,256,887
Notice both answers equal 350,256,887
With that explanation out of the way, let's continue. Next, we take the number 350,256,887 and divide it by 2:
350,256,887 ÷ 2 = 175,128,443.5
If the quotient is a whole number, then 2 and 175,128,443.5 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 | 350,256,887 | |
| -1 | -350,256,887 |
Now, we try dividing 350,256,887 by 3:
350,256,887 ÷ 3 = 116,752,295.6667
If the quotient is a whole number, then 3 and 116,752,295.6667 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 | 350,256,887 | |
| -1 | -350,256,887 |
Let's try dividing by 4:
350,256,887 ÷ 4 = 87,564,221.75
If the quotient is a whole number, then 4 and 87,564,221.75 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 | 350,256,887 | |
| -1 | 350,256,887 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 577 | 743 | 817 | 10,963 | 14,117 | 24,811 | 31,949 | 428,711 | 471,409 | 607,031 | 8,145,509 | 18,434,573 | 350,256,887 |
| -1 | -19 | -43 | -577 | -743 | -817 | -10,963 | -14,117 | -24,811 | -31,949 | -428,711 | -471,409 | -607,031 | -8,145,509 | -18,434,573 | -350,256,887 |
