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 656,010,631, 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 | 656,010,631 | |
| -1 | -656,010,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 656,010,631.
Example:
1 x 656,010,631 = 656,010,631
and
-1 x -656,010,631 = 656,010,631
Notice both answers equal 656,010,631
With that explanation out of the way, let's continue. Next, we take the number 656,010,631 and divide it by 2:
656,010,631 ÷ 2 = 328,005,315.5
If the quotient is a whole number, then 2 and 328,005,315.5 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 | 656,010,631 | |
| -1 | -656,010,631 |
Now, we try dividing 656,010,631 by 3:
656,010,631 ÷ 3 = 218,670,210.3333
If the quotient is a whole number, then 3 and 218,670,210.3333 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 | 656,010,631 | |
| -1 | -656,010,631 |
Let's try dividing by 4:
656,010,631 ÷ 4 = 164,002,657.75
If the quotient is a whole number, then 4 and 164,002,657.75 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 | 656,010,631 | |
| -1 | 656,010,631 |
If you did it right, you will end up with this table:
| 1 | 47 | 73 | 263 | 727 | 3,431 | 12,361 | 19,199 | 34,169 | 53,071 | 191,201 | 902,353 | 2,494,337 | 8,986,447 | 13,957,673 | 656,010,631 |
| -1 | -47 | -73 | -263 | -727 | -3,431 | -12,361 | -19,199 | -34,169 | -53,071 | -191,201 | -902,353 | -2,494,337 | -8,986,447 | -13,957,673 | -656,010,631 |
