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 84,503,549, 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 | 84,503,549 | |
| -1 | -84,503,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,503,549.
Example:
1 x 84,503,549 = 84,503,549
and
-1 x -84,503,549 = 84,503,549
Notice both answers equal 84,503,549
With that explanation out of the way, let's continue. Next, we take the number 84,503,549 and divide it by 2:
84,503,549 ÷ 2 = 42,251,774.5
If the quotient is a whole number, then 2 and 42,251,774.5 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 | 84,503,549 | |
| -1 | -84,503,549 |
Now, we try dividing 84,503,549 by 3:
84,503,549 ÷ 3 = 28,167,849.6667
If the quotient is a whole number, then 3 and 28,167,849.6667 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 | 84,503,549 | |
| -1 | -84,503,549 |
Let's try dividing by 4:
84,503,549 ÷ 4 = 21,125,887.25
If the quotient is a whole number, then 4 and 21,125,887.25 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 | 84,503,549 | |
| -1 | 84,503,549 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 67 | 169 | 221 | 439 | 871 | 1,139 | 2,873 | 5,707 | 7,463 | 11,323 | 14,807 | 29,413 | 74,191 | 97,019 | 192,491 | 382,369 | 500,021 | 1,261,247 | 4,970,797 | 6,500,273 | 84,503,549 |
| -1 | -13 | -17 | -67 | -169 | -221 | -439 | -871 | -1,139 | -2,873 | -5,707 | -7,463 | -11,323 | -14,807 | -29,413 | -74,191 | -97,019 | -192,491 | -382,369 | -500,021 | -1,261,247 | -4,970,797 | -6,500,273 | -84,503,549 |
