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 351,601,855, 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 | 351,601,855 | |
| -1 | -351,601,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,601,855.
Example:
1 x 351,601,855 = 351,601,855
and
-1 x -351,601,855 = 351,601,855
Notice both answers equal 351,601,855
With that explanation out of the way, let's continue. Next, we take the number 351,601,855 and divide it by 2:
351,601,855 ÷ 2 = 175,800,927.5
If the quotient is a whole number, then 2 and 175,800,927.5 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 | 351,601,855 | |
| -1 | -351,601,855 |
Now, we try dividing 351,601,855 by 3:
351,601,855 ÷ 3 = 117,200,618.3333
If the quotient is a whole number, then 3 and 117,200,618.3333 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 | 351,601,855 | |
| -1 | -351,601,855 |
Let's try dividing by 4:
351,601,855 ÷ 4 = 87,900,463.75
If the quotient is a whole number, then 4 and 87,900,463.75 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 | 351,601,855 | |
| -1 | 351,601,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 2,255 | 155,921 | 779,605 | 1,715,131 | 6,392,761 | 8,575,655 | 31,963,805 | 70,320,371 | 351,601,855 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -2,255 | -155,921 | -779,605 | -1,715,131 | -6,392,761 | -8,575,655 | -31,963,805 | -70,320,371 | -351,601,855 |
