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 826,376,443, 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 | 826,376,443 | |
| -1 | -826,376,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 826,376,443.
Example:
1 x 826,376,443 = 826,376,443
and
-1 x -826,376,443 = 826,376,443
Notice both answers equal 826,376,443
With that explanation out of the way, let's continue. Next, we take the number 826,376,443 and divide it by 2:
826,376,443 ÷ 2 = 413,188,221.5
If the quotient is a whole number, then 2 and 413,188,221.5 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 | 826,376,443 | |
| -1 | -826,376,443 |
Now, we try dividing 826,376,443 by 3:
826,376,443 ÷ 3 = 275,458,814.3333
If the quotient is a whole number, then 3 and 275,458,814.3333 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 | 826,376,443 | |
| -1 | -826,376,443 |
Let's try dividing by 4:
826,376,443 ÷ 4 = 206,594,110.75
If the quotient is a whole number, then 4 and 206,594,110.75 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 | 826,376,443 | |
| -1 | 826,376,443 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 41 | 323 | 697 | 779 | 13,243 | 62,401 | 1,060,817 | 1,185,619 | 2,558,441 | 20,155,523 | 43,493,497 | 48,610,379 | 826,376,443 |
| -1 | -17 | -19 | -41 | -323 | -697 | -779 | -13,243 | -62,401 | -1,060,817 | -1,185,619 | -2,558,441 | -20,155,523 | -43,493,497 | -48,610,379 | -826,376,443 |
