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 826,376,747, 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 | 826,376,747 | |
| -1 | -826,376,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 826,376,747.
Example:
1 x 826,376,747 = 826,376,747
and
-1 x -826,376,747 = 826,376,747
Notice both answers equal 826,376,747
With that explanation out of the way, let's continue. Next, we take the number 826,376,747 and divide it by 2:
826,376,747 ÷ 2 = 413,188,373.5
If the quotient is a whole number, then 2 and 413,188,373.5 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 | 826,376,747 | |
| -1 | -826,376,747 |
Now, we try dividing 826,376,747 by 3:
826,376,747 ÷ 3 = 275,458,915.6667
If the quotient is a whole number, then 3 and 275,458,915.6667 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 | 826,376,747 | |
| -1 | -826,376,747 |
Let's try dividing by 4:
826,376,747 ÷ 4 = 206,594,186.75
If the quotient is a whole number, then 4 and 206,594,186.75 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 | 826,376,747 | |
| -1 | 826,376,747 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 919 | 6,433 | 6,761 | 17,461 | 47,327 | 122,227 | 128,459 | 899,213 | 6,213,359 | 43,493,513 | 118,053,821 | 826,376,747 |
| -1 | -7 | -19 | -133 | -919 | -6,433 | -6,761 | -17,461 | -47,327 | -122,227 | -128,459 | -899,213 | -6,213,359 | -43,493,513 | -118,053,821 | -826,376,747 |
