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 654,032,071, 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 | 654,032,071 | |
| -1 | -654,032,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 654,032,071.
Example:
1 x 654,032,071 = 654,032,071
and
-1 x -654,032,071 = 654,032,071
Notice both answers equal 654,032,071
With that explanation out of the way, let's continue. Next, we take the number 654,032,071 and divide it by 2:
654,032,071 ÷ 2 = 327,016,035.5
If the quotient is a whole number, then 2 and 327,016,035.5 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 | 654,032,071 | |
| -1 | -654,032,071 |
Now, we try dividing 654,032,071 by 3:
654,032,071 ÷ 3 = 218,010,690.3333
If the quotient is a whole number, then 3 and 218,010,690.3333 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 | 654,032,071 | |
| -1 | -654,032,071 |
Let's try dividing by 4:
654,032,071 ÷ 4 = 163,508,017.75
If the quotient is a whole number, then 4 and 163,508,017.75 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 | 654,032,071 | |
| -1 | 654,032,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 369,301 | 2,585,107 | 4,062,311 | 8,493,923 | 28,436,177 | 59,457,461 | 93,433,153 | 654,032,071 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -369,301 | -2,585,107 | -4,062,311 | -8,493,923 | -28,436,177 | -59,457,461 | -93,433,153 | -654,032,071 |
