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 356,725,171, 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 | 356,725,171 | |
| -1 | -356,725,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,725,171.
Example:
1 x 356,725,171 = 356,725,171
and
-1 x -356,725,171 = 356,725,171
Notice both answers equal 356,725,171
With that explanation out of the way, let's continue. Next, we take the number 356,725,171 and divide it by 2:
356,725,171 ÷ 2 = 178,362,585.5
If the quotient is a whole number, then 2 and 178,362,585.5 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 | 356,725,171 | |
| -1 | -356,725,171 |
Now, we try dividing 356,725,171 by 3:
356,725,171 ÷ 3 = 118,908,390.3333
If the quotient is a whole number, then 3 and 118,908,390.3333 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 | 356,725,171 | |
| -1 | -356,725,171 |
Let's try dividing by 4:
356,725,171 ÷ 4 = 89,181,292.75
If the quotient is a whole number, then 4 and 89,181,292.75 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 | 356,725,171 | |
| -1 | 356,725,171 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 209 | 977 | 1,747 | 10,747 | 18,563 | 19,217 | 33,193 | 204,193 | 365,123 | 1,706,819 | 18,775,009 | 32,429,561 | 356,725,171 |
| -1 | -11 | -19 | -209 | -977 | -1,747 | -10,747 | -18,563 | -19,217 | -33,193 | -204,193 | -365,123 | -1,706,819 | -18,775,009 | -32,429,561 | -356,725,171 |
