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 162,414,325, 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 | 162,414,325 | |
| -1 | -162,414,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,414,325.
Example:
1 x 162,414,325 = 162,414,325
and
-1 x -162,414,325 = 162,414,325
Notice both answers equal 162,414,325
With that explanation out of the way, let's continue. Next, we take the number 162,414,325 and divide it by 2:
162,414,325 ÷ 2 = 81,207,162.5
If the quotient is a whole number, then 2 and 81,207,162.5 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 | 162,414,325 | |
| -1 | -162,414,325 |
Now, we try dividing 162,414,325 by 3:
162,414,325 ÷ 3 = 54,138,108.3333
If the quotient is a whole number, then 3 and 54,138,108.3333 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 | 162,414,325 | |
| -1 | -162,414,325 |
Let's try dividing by 4:
162,414,325 ÷ 4 = 40,603,581.25
If the quotient is a whole number, then 4 and 40,603,581.25 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 | 162,414,325 | |
| -1 | 162,414,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 193 | 205 | 821 | 965 | 1,025 | 4,105 | 4,825 | 7,913 | 20,525 | 33,661 | 39,565 | 158,453 | 168,305 | 197,825 | 792,265 | 841,525 | 3,961,325 | 6,496,573 | 32,482,865 | 162,414,325 |
| -1 | -5 | -25 | -41 | -193 | -205 | -821 | -965 | -1,025 | -4,105 | -4,825 | -7,913 | -20,525 | -33,661 | -39,565 | -158,453 | -168,305 | -197,825 | -792,265 | -841,525 | -3,961,325 | -6,496,573 | -32,482,865 | -162,414,325 |
