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 165,230,611, 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 | 165,230,611 | |
| -1 | -165,230,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 165,230,611.
Example:
1 x 165,230,611 = 165,230,611
and
-1 x -165,230,611 = 165,230,611
Notice both answers equal 165,230,611
With that explanation out of the way, let's continue. Next, we take the number 165,230,611 and divide it by 2:
165,230,611 ÷ 2 = 82,615,305.5
If the quotient is a whole number, then 2 and 82,615,305.5 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 | 165,230,611 | |
| -1 | -165,230,611 |
Now, we try dividing 165,230,611 by 3:
165,230,611 ÷ 3 = 55,076,870.3333
If the quotient is a whole number, then 3 and 55,076,870.3333 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 | 165,230,611 | |
| -1 | -165,230,611 |
Let's try dividing by 4:
165,230,611 ÷ 4 = 41,307,652.75
If the quotient is a whole number, then 4 and 41,307,652.75 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 | 165,230,611 | |
| -1 | 165,230,611 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 293 | 2,051 | 3,809 | 6,197 | 26,663 | 43,379 | 80,561 | 563,927 | 1,815,721 | 12,710,047 | 23,604,373 | 165,230,611 |
| -1 | -7 | -13 | -91 | -293 | -2,051 | -3,809 | -6,197 | -26,663 | -43,379 | -80,561 | -563,927 | -1,815,721 | -12,710,047 | -23,604,373 | -165,230,611 |
