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 835,273,153, 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 | 835,273,153 | |
| -1 | -835,273,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 835,273,153.
Example:
1 x 835,273,153 = 835,273,153
and
-1 x -835,273,153 = 835,273,153
Notice both answers equal 835,273,153
With that explanation out of the way, let's continue. Next, we take the number 835,273,153 and divide it by 2:
835,273,153 ÷ 2 = 417,636,576.5
If the quotient is a whole number, then 2 and 417,636,576.5 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 | 835,273,153 | |
| -1 | -835,273,153 |
Now, we try dividing 835,273,153 by 3:
835,273,153 ÷ 3 = 278,424,384.3333
If the quotient is a whole number, then 3 and 278,424,384.3333 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 | 835,273,153 | |
| -1 | -835,273,153 |
Let's try dividing by 4:
835,273,153 ÷ 4 = 208,818,288.25
If the quotient is a whole number, then 4 and 208,818,288.25 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 | 835,273,153 | |
| -1 | 835,273,153 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 2,131 | 2,741 | 23,441 | 27,703 | 30,151 | 35,633 | 304,733 | 391,963 | 5,841,071 | 64,251,781 | 75,933,923 | 835,273,153 |
| -1 | -11 | -13 | -143 | -2,131 | -2,741 | -23,441 | -27,703 | -30,151 | -35,633 | -304,733 | -391,963 | -5,841,071 | -64,251,781 | -75,933,923 | -835,273,153 |
