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 84,090,523, 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 | 84,090,523 | |
| -1 | -84,090,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,090,523.
Example:
1 x 84,090,523 = 84,090,523
and
-1 x -84,090,523 = 84,090,523
Notice both answers equal 84,090,523
With that explanation out of the way, let's continue. Next, we take the number 84,090,523 and divide it by 2:
84,090,523 ÷ 2 = 42,045,261.5
If the quotient is a whole number, then 2 and 42,045,261.5 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 | 84,090,523 | |
| -1 | -84,090,523 |
Now, we try dividing 84,090,523 by 3:
84,090,523 ÷ 3 = 28,030,174.3333
If the quotient is a whole number, then 3 and 28,030,174.3333 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 | 84,090,523 | |
| -1 | -84,090,523 |
Let's try dividing by 4:
84,090,523 ÷ 4 = 21,022,630.75
If the quotient is a whole number, then 4 and 21,022,630.75 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 | 84,090,523 | |
| -1 | 84,090,523 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 79 | 121 | 209 | 463 | 869 | 1,501 | 2,299 | 5,093 | 8,797 | 9,559 | 16,511 | 36,577 | 56,023 | 96,767 | 181,621 | 402,347 | 694,963 | 1,064,437 | 4,425,817 | 7,644,593 | 84,090,523 |
| -1 | -11 | -19 | -79 | -121 | -209 | -463 | -869 | -1,501 | -2,299 | -5,093 | -8,797 | -9,559 | -16,511 | -36,577 | -56,023 | -96,767 | -181,621 | -402,347 | -694,963 | -1,064,437 | -4,425,817 | -7,644,593 | -84,090,523 |
