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 162,633,205, 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 | 162,633,205 | |
| -1 | -162,633,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,633,205.
Example:
1 x 162,633,205 = 162,633,205
and
-1 x -162,633,205 = 162,633,205
Notice both answers equal 162,633,205
With that explanation out of the way, let's continue. Next, we take the number 162,633,205 and divide it by 2:
162,633,205 ÷ 2 = 81,316,602.5
If the quotient is a whole number, then 2 and 81,316,602.5 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 | 162,633,205 | |
| -1 | -162,633,205 |
Now, we try dividing 162,633,205 by 3:
162,633,205 ÷ 3 = 54,211,068.3333
If the quotient is a whole number, then 3 and 54,211,068.3333 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 | 162,633,205 | |
| -1 | -162,633,205 |
Let's try dividing by 4:
162,633,205 ÷ 4 = 40,658,301.25
If the quotient is a whole number, then 4 and 40,658,301.25 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 | 162,633,205 | |
| -1 | 162,633,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 59 | 245 | 295 | 413 | 2,065 | 2,891 | 11,251 | 14,455 | 56,255 | 78,757 | 393,785 | 551,299 | 663,809 | 2,756,495 | 3,319,045 | 4,646,663 | 23,233,315 | 32,526,641 | 162,633,205 |
| -1 | -5 | -7 | -35 | -49 | -59 | -245 | -295 | -413 | -2,065 | -2,891 | -11,251 | -14,455 | -56,255 | -78,757 | -393,785 | -551,299 | -663,809 | -2,756,495 | -3,319,045 | -4,646,663 | -23,233,315 | -32,526,641 | -162,633,205 |
