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 84,015,365, 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 | 84,015,365 | |
| -1 | -84,015,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,015,365.
Example:
1 x 84,015,365 = 84,015,365
and
-1 x -84,015,365 = 84,015,365
Notice both answers equal 84,015,365
With that explanation out of the way, let's continue. Next, we take the number 84,015,365 and divide it by 2:
84,015,365 ÷ 2 = 42,007,682.5
If the quotient is a whole number, then 2 and 42,007,682.5 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 | 84,015,365 | |
| -1 | -84,015,365 |
Now, we try dividing 84,015,365 by 3:
84,015,365 ÷ 3 = 28,005,121.6667
If the quotient is a whole number, then 3 and 28,005,121.6667 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 | 84,015,365 | |
| -1 | -84,015,365 |
Let's try dividing by 4:
84,015,365 ÷ 4 = 21,003,841.25
If the quotient is a whole number, then 4 and 21,003,841.25 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 | 84,015,365 | |
| -1 | 84,015,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 33,809 | 169,045 | 236,663 | 1,183,315 | 2,400,439 | 12,002,195 | 16,803,073 | 84,015,365 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -33,809 | -169,045 | -236,663 | -1,183,315 | -2,400,439 | -12,002,195 | -16,803,073 | -84,015,365 |
