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 607,230,151, 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 | 607,230,151 | |
| -1 | -607,230,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 607,230,151.
Example:
1 x 607,230,151 = 607,230,151
and
-1 x -607,230,151 = 607,230,151
Notice both answers equal 607,230,151
With that explanation out of the way, let's continue. Next, we take the number 607,230,151 and divide it by 2:
607,230,151 ÷ 2 = 303,615,075.5
If the quotient is a whole number, then 2 and 303,615,075.5 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 | 607,230,151 | |
| -1 | -607,230,151 |
Now, we try dividing 607,230,151 by 3:
607,230,151 ÷ 3 = 202,410,050.3333
If the quotient is a whole number, then 3 and 202,410,050.3333 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 | 607,230,151 | |
| -1 | -607,230,151 |
Let's try dividing by 4:
607,230,151 ÷ 4 = 151,807,537.75
If the quotient is a whole number, then 4 and 151,807,537.75 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 | 607,230,151 | |
| -1 | 607,230,151 |
If you did it right, you will end up with this table:
| 1 | 11 | 121 | 503 | 907 | 1,331 | 5,533 | 9,977 | 60,863 | 109,747 | 456,221 | 669,493 | 1,207,217 | 5,018,431 | 55,202,741 | 607,230,151 |
| -1 | -11 | -121 | -503 | -907 | -1,331 | -5,533 | -9,977 | -60,863 | -109,747 | -456,221 | -669,493 | -1,207,217 | -5,018,431 | -55,202,741 | -607,230,151 |
