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 84,500,339, 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 | 84,500,339 | |
| -1 | -84,500,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,500,339.
Example:
1 x 84,500,339 = 84,500,339
and
-1 x -84,500,339 = 84,500,339
Notice both answers equal 84,500,339
With that explanation out of the way, let's continue. Next, we take the number 84,500,339 and divide it by 2:
84,500,339 ÷ 2 = 42,250,169.5
If the quotient is a whole number, then 2 and 42,250,169.5 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 | 84,500,339 | |
| -1 | -84,500,339 |
Now, we try dividing 84,500,339 by 3:
84,500,339 ÷ 3 = 28,166,779.6667
If the quotient is a whole number, then 3 and 28,166,779.6667 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 | 84,500,339 | |
| -1 | -84,500,339 |
Let's try dividing by 4:
84,500,339 ÷ 4 = 21,125,084.75
If the quotient is a whole number, then 4 and 21,125,084.75 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 | 84,500,339 | |
| -1 | 84,500,339 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 127 | 889 | 1,397 | 8,641 | 9,779 | 60,487 | 95,051 | 665,357 | 1,097,407 | 7,681,849 | 12,071,477 | 84,500,339 |
| -1 | -7 | -11 | -77 | -127 | -889 | -1,397 | -8,641 | -9,779 | -60,487 | -95,051 | -665,357 | -1,097,407 | -7,681,849 | -12,071,477 | -84,500,339 |
