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 151,600,163, 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 | 151,600,163 | |
| -1 | -151,600,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,600,163.
Example:
1 x 151,600,163 = 151,600,163
and
-1 x -151,600,163 = 151,600,163
Notice both answers equal 151,600,163
With that explanation out of the way, let's continue. Next, we take the number 151,600,163 and divide it by 2:
151,600,163 ÷ 2 = 75,800,081.5
If the quotient is a whole number, then 2 and 75,800,081.5 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 | 151,600,163 | |
| -1 | -151,600,163 |
Now, we try dividing 151,600,163 by 3:
151,600,163 ÷ 3 = 50,533,387.6667
If the quotient is a whole number, then 3 and 50,533,387.6667 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 | 151,600,163 | |
| -1 | -151,600,163 |
Let's try dividing by 4:
151,600,163 ÷ 4 = 37,900,040.75
If the quotient is a whole number, then 4 and 37,900,040.75 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 | 151,600,163 | |
| -1 | 151,600,163 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 67 | 143 | 737 | 871 | 9,581 | 15,823 | 174,053 | 205,699 | 1,060,141 | 2,262,689 | 11,661,551 | 13,781,833 | 151,600,163 |
| -1 | -11 | -13 | -67 | -143 | -737 | -871 | -9,581 | -15,823 | -174,053 | -205,699 | -1,060,141 | -2,262,689 | -11,661,551 | -13,781,833 | -151,600,163 |
