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 84,437,755, 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 | 84,437,755 | |
| -1 | -84,437,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,437,755.
Example:
1 x 84,437,755 = 84,437,755
and
-1 x -84,437,755 = 84,437,755
Notice both answers equal 84,437,755
With that explanation out of the way, let's continue. Next, we take the number 84,437,755 and divide it by 2:
84,437,755 ÷ 2 = 42,218,877.5
If the quotient is a whole number, then 2 and 42,218,877.5 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 | 84,437,755 | |
| -1 | -84,437,755 |
Now, we try dividing 84,437,755 by 3:
84,437,755 ÷ 3 = 28,145,918.3333
If the quotient is a whole number, then 3 and 28,145,918.3333 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 | 84,437,755 | |
| -1 | -84,437,755 |
Let's try dividing by 4:
84,437,755 ÷ 4 = 21,109,438.75
If the quotient is a whole number, then 4 and 21,109,438.75 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 | 84,437,755 | |
| -1 | 84,437,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 269 | 335 | 937 | 1,345 | 4,685 | 18,023 | 62,779 | 90,115 | 252,053 | 313,895 | 1,260,265 | 16,887,551 | 84,437,755 |
| -1 | -5 | -67 | -269 | -335 | -937 | -1,345 | -4,685 | -18,023 | -62,779 | -90,115 | -252,053 | -313,895 | -1,260,265 | -16,887,551 | -84,437,755 |
