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 675,015,013, 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 | 675,015,013 | |
| -1 | -675,015,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 675,015,013.
Example:
1 x 675,015,013 = 675,015,013
and
-1 x -675,015,013 = 675,015,013
Notice both answers equal 675,015,013
With that explanation out of the way, let's continue. Next, we take the number 675,015,013 and divide it by 2:
675,015,013 ÷ 2 = 337,507,506.5
If the quotient is a whole number, then 2 and 337,507,506.5 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 | 675,015,013 | |
| -1 | -675,015,013 |
Now, we try dividing 675,015,013 by 3:
675,015,013 ÷ 3 = 225,005,004.3333
If the quotient is a whole number, then 3 and 225,005,004.3333 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 | 675,015,013 | |
| -1 | -675,015,013 |
Let's try dividing by 4:
675,015,013 ÷ 4 = 168,753,753.25
If the quotient is a whole number, then 4 and 168,753,753.25 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 | 675,015,013 | |
| -1 | 675,015,013 |
If you did it right, you will end up with this table:
| 1 | 37 | 73 | 83 | 2,701 | 3,011 | 3,071 | 6,059 | 111,407 | 219,803 | 224,183 | 249,913 | 8,132,711 | 9,246,781 | 18,243,649 | 675,015,013 |
| -1 | -37 | -73 | -83 | -2,701 | -3,011 | -3,071 | -6,059 | -111,407 | -219,803 | -224,183 | -249,913 | -8,132,711 | -9,246,781 | -18,243,649 | -675,015,013 |
