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 84,402,101, 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 | 84,402,101 | |
| -1 | -84,402,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,402,101.
Example:
1 x 84,402,101 = 84,402,101
and
-1 x -84,402,101 = 84,402,101
Notice both answers equal 84,402,101
With that explanation out of the way, let's continue. Next, we take the number 84,402,101 and divide it by 2:
84,402,101 ÷ 2 = 42,201,050.5
If the quotient is a whole number, then 2 and 42,201,050.5 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 | 84,402,101 | |
| -1 | -84,402,101 |
Now, we try dividing 84,402,101 by 3:
84,402,101 ÷ 3 = 28,134,033.6667
If the quotient is a whole number, then 3 and 28,134,033.6667 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 | 84,402,101 | |
| -1 | -84,402,101 |
Let's try dividing by 4:
84,402,101 ÷ 4 = 21,100,525.25
If the quotient is a whole number, then 4 and 21,100,525.25 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 | 84,402,101 | |
| -1 | 84,402,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 157 | 427 | 1,099 | 1,259 | 8,813 | 9,577 | 67,039 | 76,799 | 197,663 | 537,593 | 1,383,641 | 12,057,443 | 84,402,101 |
| -1 | -7 | -61 | -157 | -427 | -1,099 | -1,259 | -8,813 | -9,577 | -67,039 | -76,799 | -197,663 | -537,593 | -1,383,641 | -12,057,443 | -84,402,101 |
