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 162,415,603, 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 | 162,415,603 | |
| -1 | -162,415,603 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,415,603.
Example:
1 x 162,415,603 = 162,415,603
and
-1 x -162,415,603 = 162,415,603
Notice both answers equal 162,415,603
With that explanation out of the way, let's continue. Next, we take the number 162,415,603 and divide it by 2:
162,415,603 ÷ 2 = 81,207,801.5
If the quotient is a whole number, then 2 and 81,207,801.5 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 | 162,415,603 | |
| -1 | -162,415,603 |
Now, we try dividing 162,415,603 by 3:
162,415,603 ÷ 3 = 54,138,534.3333
If the quotient is a whole number, then 3 and 54,138,534.3333 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 | 162,415,603 | |
| -1 | -162,415,603 |
Let's try dividing by 4:
162,415,603 ÷ 4 = 40,603,900.75
If the quotient is a whole number, then 4 and 40,603,900.75 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 | 162,415,603 | |
| -1 | 162,415,603 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 31 | 119 | 217 | 527 | 3,689 | 44,027 | 308,189 | 748,459 | 1,364,837 | 5,239,213 | 9,553,859 | 23,202,229 | 162,415,603 |
| -1 | -7 | -17 | -31 | -119 | -217 | -527 | -3,689 | -44,027 | -308,189 | -748,459 | -1,364,837 | -5,239,213 | -9,553,859 | -23,202,229 | -162,415,603 |
