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 834,448,519, 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 | 834,448,519 | |
| -1 | -834,448,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 834,448,519.
Example:
1 x 834,448,519 = 834,448,519
and
-1 x -834,448,519 = 834,448,519
Notice both answers equal 834,448,519
With that explanation out of the way, let's continue. Next, we take the number 834,448,519 and divide it by 2:
834,448,519 ÷ 2 = 417,224,259.5
If the quotient is a whole number, then 2 and 417,224,259.5 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 | 834,448,519 | |
| -1 | -834,448,519 |
Now, we try dividing 834,448,519 by 3:
834,448,519 ÷ 3 = 278,149,506.3333
If the quotient is a whole number, then 3 and 278,149,506.3333 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 | 834,448,519 | |
| -1 | -834,448,519 |
Let's try dividing by 4:
834,448,519 ÷ 4 = 208,612,129.75
If the quotient is a whole number, then 4 and 208,612,129.75 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 | 834,448,519 | |
| -1 | 834,448,519 |
If you did it right, you will end up with this table:
| 1 | 17 | 109 | 401 | 1,123 | 1,853 | 6,817 | 19,091 | 43,709 | 122,407 | 450,323 | 743,053 | 2,080,919 | 7,655,491 | 49,085,207 | 834,448,519 |
| -1 | -17 | -109 | -401 | -1,123 | -1,853 | -6,817 | -19,091 | -43,709 | -122,407 | -450,323 | -743,053 | -2,080,919 | -7,655,491 | -49,085,207 | -834,448,519 |
