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 162,604,645, 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 | 162,604,645 | |
| -1 | -162,604,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,604,645.
Example:
1 x 162,604,645 = 162,604,645
and
-1 x -162,604,645 = 162,604,645
Notice both answers equal 162,604,645
With that explanation out of the way, let's continue. Next, we take the number 162,604,645 and divide it by 2:
162,604,645 ÷ 2 = 81,302,322.5
If the quotient is a whole number, then 2 and 81,302,322.5 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 | 162,604,645 | |
| -1 | -162,604,645 |
Now, we try dividing 162,604,645 by 3:
162,604,645 ÷ 3 = 54,201,548.3333
If the quotient is a whole number, then 3 and 54,201,548.3333 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 | 162,604,645 | |
| -1 | -162,604,645 |
Let's try dividing by 4:
162,604,645 ÷ 4 = 40,651,161.25
If the quotient is a whole number, then 4 and 40,651,161.25 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 | 162,604,645 | |
| -1 | 162,604,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 67 | 335 | 469 | 2,345 | 69,341 | 346,705 | 485,387 | 2,426,935 | 4,645,847 | 23,229,235 | 32,520,929 | 162,604,645 |
| -1 | -5 | -7 | -35 | -67 | -335 | -469 | -2,345 | -69,341 | -346,705 | -485,387 | -2,426,935 | -4,645,847 | -23,229,235 | -32,520,929 | -162,604,645 |
