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 162,603,265, 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 | 162,603,265 | |
| -1 | -162,603,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,603,265.
Example:
1 x 162,603,265 = 162,603,265
and
-1 x -162,603,265 = 162,603,265
Notice both answers equal 162,603,265
With that explanation out of the way, let's continue. Next, we take the number 162,603,265 and divide it by 2:
162,603,265 ÷ 2 = 81,301,632.5
If the quotient is a whole number, then 2 and 81,301,632.5 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 | 162,603,265 | |
| -1 | -162,603,265 |
Now, we try dividing 162,603,265 by 3:
162,603,265 ÷ 3 = 54,201,088.3333
If the quotient is a whole number, then 3 and 54,201,088.3333 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 | 162,603,265 | |
| -1 | -162,603,265 |
Let's try dividing by 4:
162,603,265 ÷ 4 = 40,650,816.25
If the quotient is a whole number, then 4 and 40,650,816.25 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 | 162,603,265 | |
| -1 | 162,603,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 919 | 3,217 | 4,595 | 10,109 | 16,085 | 35,387 | 50,545 | 176,935 | 2,956,423 | 14,782,115 | 32,520,653 | 162,603,265 |
| -1 | -5 | -11 | -55 | -919 | -3,217 | -4,595 | -10,109 | -16,085 | -35,387 | -50,545 | -176,935 | -2,956,423 | -14,782,115 | -32,520,653 | -162,603,265 |
