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 164,305,537, 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 | 164,305,537 | |
| -1 | -164,305,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,305,537.
Example:
1 x 164,305,537 = 164,305,537
and
-1 x -164,305,537 = 164,305,537
Notice both answers equal 164,305,537
With that explanation out of the way, let's continue. Next, we take the number 164,305,537 and divide it by 2:
164,305,537 ÷ 2 = 82,152,768.5
If the quotient is a whole number, then 2 and 82,152,768.5 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 | 164,305,537 | |
| -1 | -164,305,537 |
Now, we try dividing 164,305,537 by 3:
164,305,537 ÷ 3 = 54,768,512.3333
If the quotient is a whole number, then 3 and 54,768,512.3333 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 | 164,305,537 | |
| -1 | -164,305,537 |
Let's try dividing by 4:
164,305,537 ÷ 4 = 41,076,384.25
If the quotient is a whole number, then 4 and 41,076,384.25 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 | 164,305,537 | |
| -1 | 164,305,537 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 43 | 121 | 253 | 473 | 989 | 1,373 | 2,783 | 5,203 | 10,879 | 15,103 | 31,579 | 59,039 | 119,669 | 166,133 | 347,369 | 649,429 | 1,357,897 | 3,821,059 | 7,143,719 | 14,936,867 | 164,305,537 |
| -1 | -11 | -23 | -43 | -121 | -253 | -473 | -989 | -1,373 | -2,783 | -5,203 | -10,879 | -15,103 | -31,579 | -59,039 | -119,669 | -166,133 | -347,369 | -649,429 | -1,357,897 | -3,821,059 | -7,143,719 | -14,936,867 | -164,305,537 |
