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 363,349,355, 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 | 363,349,355 | |
| -1 | -363,349,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 363,349,355.
Example:
1 x 363,349,355 = 363,349,355
and
-1 x -363,349,355 = 363,349,355
Notice both answers equal 363,349,355
With that explanation out of the way, let's continue. Next, we take the number 363,349,355 and divide it by 2:
363,349,355 ÷ 2 = 181,674,677.5
If the quotient is a whole number, then 2 and 181,674,677.5 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 | 363,349,355 | |
| -1 | -363,349,355 |
Now, we try dividing 363,349,355 by 3:
363,349,355 ÷ 3 = 121,116,451.6667
If the quotient is a whole number, then 3 and 121,116,451.6667 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 | 363,349,355 | |
| -1 | -363,349,355 |
Let's try dividing by 4:
363,349,355 ÷ 4 = 90,837,338.75
If the quotient is a whole number, then 4 and 90,837,338.75 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 | 363,349,355 | |
| -1 | 363,349,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 181 | 215 | 905 | 7,783 | 9,337 | 38,915 | 46,685 | 401,491 | 1,689,997 | 2,007,455 | 8,449,985 | 72,669,871 | 363,349,355 |
| -1 | -5 | -43 | -181 | -215 | -905 | -7,783 | -9,337 | -38,915 | -46,685 | -401,491 | -1,689,997 | -2,007,455 | -8,449,985 | -72,669,871 | -363,349,355 |
