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 151,351,505, 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 | 151,351,505 | |
| -1 | -151,351,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,351,505.
Example:
1 x 151,351,505 = 151,351,505
and
-1 x -151,351,505 = 151,351,505
Notice both answers equal 151,351,505
With that explanation out of the way, let's continue. Next, we take the number 151,351,505 and divide it by 2:
151,351,505 ÷ 2 = 75,675,752.5
If the quotient is a whole number, then 2 and 75,675,752.5 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 | 151,351,505 | |
| -1 | -151,351,505 |
Now, we try dividing 151,351,505 by 3:
151,351,505 ÷ 3 = 50,450,501.6667
If the quotient is a whole number, then 3 and 50,450,501.6667 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 | 151,351,505 | |
| -1 | -151,351,505 |
Let's try dividing by 4:
151,351,505 ÷ 4 = 37,837,876.25
If the quotient is a whole number, then 4 and 37,837,876.25 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 | 151,351,505 | |
| -1 | 151,351,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 131 | 269 | 655 | 859 | 1,345 | 4,295 | 35,239 | 112,529 | 176,195 | 231,071 | 562,645 | 1,155,355 | 30,270,301 | 151,351,505 |
| -1 | -5 | -131 | -269 | -655 | -859 | -1,345 | -4,295 | -35,239 | -112,529 | -176,195 | -231,071 | -562,645 | -1,155,355 | -30,270,301 | -151,351,505 |
