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 304,422,155, 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 | 304,422,155 | |
| -1 | -304,422,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,422,155.
Example:
1 x 304,422,155 = 304,422,155
and
-1 x -304,422,155 = 304,422,155
Notice both answers equal 304,422,155
With that explanation out of the way, let's continue. Next, we take the number 304,422,155 and divide it by 2:
304,422,155 ÷ 2 = 152,211,077.5
If the quotient is a whole number, then 2 and 152,211,077.5 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 | 304,422,155 | |
| -1 | -304,422,155 |
Now, we try dividing 304,422,155 by 3:
304,422,155 ÷ 3 = 101,474,051.6667
If the quotient is a whole number, then 3 and 101,474,051.6667 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 | 304,422,155 | |
| -1 | -304,422,155 |
Let's try dividing by 4:
304,422,155 ÷ 4 = 76,105,538.75
If the quotient is a whole number, then 4 and 76,105,538.75 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 | 304,422,155 | |
| -1 | 304,422,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 79 | 215 | 395 | 3,397 | 16,985 | 17,923 | 89,615 | 770,689 | 1,415,917 | 3,853,445 | 7,079,585 | 60,884,431 | 304,422,155 |
| -1 | -5 | -43 | -79 | -215 | -395 | -3,397 | -16,985 | -17,923 | -89,615 | -770,689 | -1,415,917 | -3,853,445 | -7,079,585 | -60,884,431 | -304,422,155 |
