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 84,680,045, 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 | 84,680,045 | |
| -1 | -84,680,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,680,045.
Example:
1 x 84,680,045 = 84,680,045
and
-1 x -84,680,045 = 84,680,045
Notice both answers equal 84,680,045
With that explanation out of the way, let's continue. Next, we take the number 84,680,045 and divide it by 2:
84,680,045 ÷ 2 = 42,340,022.5
If the quotient is a whole number, then 2 and 42,340,022.5 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 | 84,680,045 | |
| -1 | -84,680,045 |
Now, we try dividing 84,680,045 by 3:
84,680,045 ÷ 3 = 28,226,681.6667
If the quotient is a whole number, then 3 and 28,226,681.6667 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 | 84,680,045 | |
| -1 | -84,680,045 |
Let's try dividing by 4:
84,680,045 ÷ 4 = 21,170,011.25
If the quotient is a whole number, then 4 and 21,170,011.25 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 | 84,680,045 | |
| -1 | 84,680,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 151 | 295 | 755 | 1,901 | 8,909 | 9,505 | 44,545 | 112,159 | 287,051 | 560,795 | 1,435,255 | 16,936,009 | 84,680,045 |
| -1 | -5 | -59 | -151 | -295 | -755 | -1,901 | -8,909 | -9,505 | -44,545 | -112,159 | -287,051 | -560,795 | -1,435,255 | -16,936,009 | -84,680,045 |
