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 654,004,645, 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 | 654,004,645 | |
| -1 | -654,004,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 654,004,645.
Example:
1 x 654,004,645 = 654,004,645
and
-1 x -654,004,645 = 654,004,645
Notice both answers equal 654,004,645
With that explanation out of the way, let's continue. Next, we take the number 654,004,645 and divide it by 2:
654,004,645 ÷ 2 = 327,002,322.5
If the quotient is a whole number, then 2 and 327,002,322.5 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 | 654,004,645 | |
| -1 | -654,004,645 |
Now, we try dividing 654,004,645 by 3:
654,004,645 ÷ 3 = 218,001,548.3333
If the quotient is a whole number, then 3 and 218,001,548.3333 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 | 654,004,645 | |
| -1 | -654,004,645 |
Let's try dividing by 4:
654,004,645 ÷ 4 = 163,501,161.25
If the quotient is a whole number, then 4 and 163,501,161.25 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 | 654,004,645 | |
| -1 | 654,004,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 983 | 4,915 | 6,881 | 19,009 | 34,405 | 95,045 | 133,063 | 665,315 | 18,685,847 | 93,429,235 | 130,800,929 | 654,004,645 |
| -1 | -5 | -7 | -35 | -983 | -4,915 | -6,881 | -19,009 | -34,405 | -95,045 | -133,063 | -665,315 | -18,685,847 | -93,429,235 | -130,800,929 | -654,004,645 |
