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 356,527,717, 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 | 356,527,717 | |
| -1 | -356,527,717 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,527,717.
Example:
1 x 356,527,717 = 356,527,717
and
-1 x -356,527,717 = 356,527,717
Notice both answers equal 356,527,717
With that explanation out of the way, let's continue. Next, we take the number 356,527,717 and divide it by 2:
356,527,717 ÷ 2 = 178,263,858.5
If the quotient is a whole number, then 2 and 178,263,858.5 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 | 356,527,717 | |
| -1 | -356,527,717 |
Now, we try dividing 356,527,717 by 3:
356,527,717 ÷ 3 = 118,842,572.3333
If the quotient is a whole number, then 3 and 118,842,572.3333 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 | 356,527,717 | |
| -1 | -356,527,717 |
Let's try dividing by 4:
356,527,717 ÷ 4 = 89,131,929.25
If the quotient is a whole number, then 4 and 89,131,929.25 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 | 356,527,717 | |
| -1 | 356,527,717 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 223 | 1,561 | 2,899 | 17,569 | 20,293 | 122,983 | 228,397 | 1,598,779 | 3,917,887 | 27,425,209 | 50,932,531 | 356,527,717 |
| -1 | -7 | -13 | -91 | -223 | -1,561 | -2,899 | -17,569 | -20,293 | -122,983 | -228,397 | -1,598,779 | -3,917,887 | -27,425,209 | -50,932,531 | -356,527,717 |
