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 152,504,161, 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 | 152,504,161 | |
| -1 | -152,504,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,504,161.
Example:
1 x 152,504,161 = 152,504,161
and
-1 x -152,504,161 = 152,504,161
Notice both answers equal 152,504,161
With that explanation out of the way, let's continue. Next, we take the number 152,504,161 and divide it by 2:
152,504,161 ÷ 2 = 76,252,080.5
If the quotient is a whole number, then 2 and 76,252,080.5 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 | 152,504,161 | |
| -1 | -152,504,161 |
Now, we try dividing 152,504,161 by 3:
152,504,161 ÷ 3 = 50,834,720.3333
If the quotient is a whole number, then 3 and 50,834,720.3333 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 | 152,504,161 | |
| -1 | -152,504,161 |
Let's try dividing by 4:
152,504,161 ÷ 4 = 38,126,040.25
If the quotient is a whole number, then 4 and 38,126,040.25 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 | 152,504,161 | |
| -1 | 152,504,161 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 193 | 877 | 901 | 3,281 | 10,229 | 14,909 | 46,481 | 169,261 | 173,893 | 790,177 | 2,877,437 | 8,970,833 | 152,504,161 |
| -1 | -17 | -53 | -193 | -877 | -901 | -3,281 | -10,229 | -14,909 | -46,481 | -169,261 | -173,893 | -790,177 | -2,877,437 | -8,970,833 | -152,504,161 |
