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 351,156,355, 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 | 351,156,355 | |
| -1 | -351,156,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,156,355.
Example:
1 x 351,156,355 = 351,156,355
and
-1 x -351,156,355 = 351,156,355
Notice both answers equal 351,156,355
With that explanation out of the way, let's continue. Next, we take the number 351,156,355 and divide it by 2:
351,156,355 ÷ 2 = 175,578,177.5
If the quotient is a whole number, then 2 and 175,578,177.5 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 | 351,156,355 | |
| -1 | -351,156,355 |
Now, we try dividing 351,156,355 by 3:
351,156,355 ÷ 3 = 117,052,118.3333
If the quotient is a whole number, then 3 and 117,052,118.3333 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 | 351,156,355 | |
| -1 | -351,156,355 |
Let's try dividing by 4:
351,156,355 ÷ 4 = 87,789,088.75
If the quotient is a whole number, then 4 and 87,789,088.75 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 | 351,156,355 | |
| -1 | 351,156,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 103 | 515 | 1,133 | 5,665 | 61,987 | 309,935 | 681,857 | 3,409,285 | 6,384,661 | 31,923,305 | 70,231,271 | 351,156,355 |
| -1 | -5 | -11 | -55 | -103 | -515 | -1,133 | -5,665 | -61,987 | -309,935 | -681,857 | -3,409,285 | -6,384,661 | -31,923,305 | -70,231,271 | -351,156,355 |
