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 86,484,223, 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 | 86,484,223 | |
| -1 | -86,484,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 86,484,223.
Example:
1 x 86,484,223 = 86,484,223
and
-1 x -86,484,223 = 86,484,223
Notice both answers equal 86,484,223
With that explanation out of the way, let's continue. Next, we take the number 86,484,223 and divide it by 2:
86,484,223 ÷ 2 = 43,242,111.5
If the quotient is a whole number, then 2 and 43,242,111.5 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 | 86,484,223 | |
| -1 | -86,484,223 |
Now, we try dividing 86,484,223 by 3:
86,484,223 ÷ 3 = 28,828,074.3333
If the quotient is a whole number, then 3 and 28,828,074.3333 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 | 86,484,223 | |
| -1 | -86,484,223 |
Let's try dividing by 4:
86,484,223 ÷ 4 = 21,621,055.75
If the quotient is a whole number, then 4 and 21,621,055.75 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 | 86,484,223 | |
| -1 | 86,484,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 79 | 301 | 553 | 3,397 | 3,637 | 23,779 | 25,459 | 156,391 | 287,323 | 1,094,737 | 2,011,261 | 12,354,889 | 86,484,223 |
| -1 | -7 | -43 | -79 | -301 | -553 | -3,397 | -3,637 | -23,779 | -25,459 | -156,391 | -287,323 | -1,094,737 | -2,011,261 | -12,354,889 | -86,484,223 |
