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 604,022,155, 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 | 604,022,155 | |
| -1 | -604,022,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 604,022,155.
Example:
1 x 604,022,155 = 604,022,155
and
-1 x -604,022,155 = 604,022,155
Notice both answers equal 604,022,155
With that explanation out of the way, let's continue. Next, we take the number 604,022,155 and divide it by 2:
604,022,155 ÷ 2 = 302,011,077.5
If the quotient is a whole number, then 2 and 302,011,077.5 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 | 604,022,155 | |
| -1 | -604,022,155 |
Now, we try dividing 604,022,155 by 3:
604,022,155 ÷ 3 = 201,340,718.3333
If the quotient is a whole number, then 3 and 201,340,718.3333 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 | 604,022,155 | |
| -1 | -604,022,155 |
Let's try dividing by 4:
604,022,155 ÷ 4 = 151,005,538.75
If the quotient is a whole number, then 4 and 151,005,538.75 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 | 604,022,155 | |
| -1 | 604,022,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 646,013 | 3,230,065 | 7,106,143 | 10,982,221 | 35,530,715 | 54,911,105 | 120,804,431 | 604,022,155 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -646,013 | -3,230,065 | -7,106,143 | -10,982,221 | -35,530,715 | -54,911,105 | -120,804,431 | -604,022,155 |
