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 654,446,161, 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 | 654,446,161 | |
| -1 | -654,446,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 654,446,161.
Example:
1 x 654,446,161 = 654,446,161
and
-1 x -654,446,161 = 654,446,161
Notice both answers equal 654,446,161
With that explanation out of the way, let's continue. Next, we take the number 654,446,161 and divide it by 2:
654,446,161 ÷ 2 = 327,223,080.5
If the quotient is a whole number, then 2 and 327,223,080.5 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 | 654,446,161 | |
| -1 | -654,446,161 |
Now, we try dividing 654,446,161 by 3:
654,446,161 ÷ 3 = 218,148,720.3333
If the quotient is a whole number, then 3 and 218,148,720.3333 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 | 654,446,161 | |
| -1 | -654,446,161 |
Let's try dividing by 4:
654,446,161 ÷ 4 = 163,611,540.25
If the quotient is a whole number, then 4 and 163,611,540.25 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 | 654,446,161 | |
| -1 | 654,446,161 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 493 | 569 | 2,333 | 9,673 | 16,501 | 39,661 | 67,657 | 280,517 | 1,150,169 | 1,327,477 | 22,567,109 | 38,496,833 | 654,446,161 |
| -1 | -17 | -29 | -493 | -569 | -2,333 | -9,673 | -16,501 | -39,661 | -67,657 | -280,517 | -1,150,169 | -1,327,477 | -22,567,109 | -38,496,833 | -654,446,161 |
