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 84,104,675, 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 | 84,104,675 | |
| -1 | -84,104,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,104,675.
Example:
1 x 84,104,675 = 84,104,675
and
-1 x -84,104,675 = 84,104,675
Notice both answers equal 84,104,675
With that explanation out of the way, let's continue. Next, we take the number 84,104,675 and divide it by 2:
84,104,675 ÷ 2 = 42,052,337.5
If the quotient is a whole number, then 2 and 42,052,337.5 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 | 84,104,675 | |
| -1 | -84,104,675 |
Now, we try dividing 84,104,675 by 3:
84,104,675 ÷ 3 = 28,034,891.6667
If the quotient is a whole number, then 3 and 28,034,891.6667 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 | 84,104,675 | |
| -1 | -84,104,675 |
Let's try dividing by 4:
84,104,675 ÷ 4 = 21,026,168.75
If the quotient is a whole number, then 4 and 21,026,168.75 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 | 84,104,675 | |
| -1 | 84,104,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 107 | 115 | 535 | 575 | 1,367 | 2,461 | 2,675 | 6,835 | 12,305 | 31,441 | 34,175 | 61,525 | 146,269 | 157,205 | 731,345 | 786,025 | 3,364,187 | 3,656,725 | 16,820,935 | 84,104,675 |
| -1 | -5 | -23 | -25 | -107 | -115 | -535 | -575 | -1,367 | -2,461 | -2,675 | -6,835 | -12,305 | -31,441 | -34,175 | -61,525 | -146,269 | -157,205 | -731,345 | -786,025 | -3,364,187 | -3,656,725 | -16,820,935 | -84,104,675 |
