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 156,184,085, 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 | 156,184,085 | |
| -1 | -156,184,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,184,085.
Example:
1 x 156,184,085 = 156,184,085
and
-1 x -156,184,085 = 156,184,085
Notice both answers equal 156,184,085
With that explanation out of the way, let's continue. Next, we take the number 156,184,085 and divide it by 2:
156,184,085 ÷ 2 = 78,092,042.5
If the quotient is a whole number, then 2 and 78,092,042.5 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 | 156,184,085 | |
| -1 | -156,184,085 |
Now, we try dividing 156,184,085 by 3:
156,184,085 ÷ 3 = 52,061,361.6667
If the quotient is a whole number, then 3 and 52,061,361.6667 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 | 156,184,085 | |
| -1 | -156,184,085 |
Let's try dividing by 4:
156,184,085 ÷ 4 = 39,046,021.25
If the quotient is a whole number, then 4 and 39,046,021.25 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 | 156,184,085 | |
| -1 | 156,184,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 787 | 2,089 | 3,935 | 10,445 | 14,953 | 39,691 | 74,765 | 198,455 | 1,644,043 | 8,220,215 | 31,236,817 | 156,184,085 |
| -1 | -5 | -19 | -95 | -787 | -2,089 | -3,935 | -10,445 | -14,953 | -39,691 | -74,765 | -198,455 | -1,644,043 | -8,220,215 | -31,236,817 | -156,184,085 |
