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 824,784,529, 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 | 824,784,529 | |
| -1 | -824,784,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 824,784,529.
Example:
1 x 824,784,529 = 824,784,529
and
-1 x -824,784,529 = 824,784,529
Notice both answers equal 824,784,529
With that explanation out of the way, let's continue. Next, we take the number 824,784,529 and divide it by 2:
824,784,529 ÷ 2 = 412,392,264.5
If the quotient is a whole number, then 2 and 412,392,264.5 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 | 824,784,529 | |
| -1 | -824,784,529 |
Now, we try dividing 824,784,529 by 3:
824,784,529 ÷ 3 = 274,928,176.3333
If the quotient is a whole number, then 3 and 274,928,176.3333 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 | 824,784,529 | |
| -1 | -824,784,529 |
Let's try dividing by 4:
824,784,529 ÷ 4 = 206,196,132.25
If the quotient is a whole number, then 4 and 206,196,132.25 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 | 824,784,529 | |
| -1 | 824,784,529 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 83 | 799 | 1,411 | 3,901 | 12,437 | 66,317 | 211,429 | 584,539 | 1,032,271 | 9,937,163 | 17,548,607 | 48,516,737 | 824,784,529 |
| -1 | -17 | -47 | -83 | -799 | -1,411 | -3,901 | -12,437 | -66,317 | -211,429 | -584,539 | -1,032,271 | -9,937,163 | -17,548,607 | -48,516,737 | -824,784,529 |
