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 151,606,327, 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 | 151,606,327 | |
| -1 | -151,606,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,606,327.
Example:
1 x 151,606,327 = 151,606,327
and
-1 x -151,606,327 = 151,606,327
Notice both answers equal 151,606,327
With that explanation out of the way, let's continue. Next, we take the number 151,606,327 and divide it by 2:
151,606,327 ÷ 2 = 75,803,163.5
If the quotient is a whole number, then 2 and 75,803,163.5 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 | 151,606,327 | |
| -1 | -151,606,327 |
Now, we try dividing 151,606,327 by 3:
151,606,327 ÷ 3 = 50,535,442.3333
If the quotient is a whole number, then 3 and 50,535,442.3333 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 | 151,606,327 | |
| -1 | -151,606,327 |
Let's try dividing by 4:
151,606,327 ÷ 4 = 37,901,581.75
If the quotient is a whole number, then 4 and 37,901,581.75 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 | 151,606,327 | |
| -1 | 151,606,327 |
If you did it right, you will end up with this table:
| 1 | 67 | 73 | 139 | 223 | 4,891 | 9,313 | 10,147 | 14,941 | 16,279 | 30,997 | 679,849 | 1,090,693 | 2,076,799 | 2,262,781 | 151,606,327 |
| -1 | -67 | -73 | -139 | -223 | -4,891 | -9,313 | -10,147 | -14,941 | -16,279 | -30,997 | -679,849 | -1,090,693 | -2,076,799 | -2,262,781 | -151,606,327 |
