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 164,320,057, 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 | 164,320,057 | |
| -1 | -164,320,057 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,320,057.
Example:
1 x 164,320,057 = 164,320,057
and
-1 x -164,320,057 = 164,320,057
Notice both answers equal 164,320,057
With that explanation out of the way, let's continue. Next, we take the number 164,320,057 and divide it by 2:
164,320,057 ÷ 2 = 82,160,028.5
If the quotient is a whole number, then 2 and 82,160,028.5 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 | 164,320,057 | |
| -1 | -164,320,057 |
Now, we try dividing 164,320,057 by 3:
164,320,057 ÷ 3 = 54,773,352.3333
If the quotient is a whole number, then 3 and 54,773,352.3333 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 | 164,320,057 | |
| -1 | -164,320,057 |
Let's try dividing by 4:
164,320,057 ÷ 4 = 41,080,014.25
If the quotient is a whole number, then 4 and 41,080,014.25 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 | 164,320,057 | |
| -1 | 164,320,057 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 71 | 121 | 341 | 617 | 781 | 2,201 | 3,751 | 6,787 | 8,591 | 19,127 | 24,211 | 43,807 | 74,657 | 210,397 | 266,321 | 481,877 | 1,358,017 | 2,314,367 | 5,300,647 | 14,938,187 | 164,320,057 |
| -1 | -11 | -31 | -71 | -121 | -341 | -617 | -781 | -2,201 | -3,751 | -6,787 | -8,591 | -19,127 | -24,211 | -43,807 | -74,657 | -210,397 | -266,321 | -481,877 | -1,358,017 | -2,314,367 | -5,300,647 | -14,938,187 | -164,320,057 |
