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 164,075,143, 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 | 164,075,143 | |
| -1 | -164,075,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 164,075,143.
Example:
1 x 164,075,143 = 164,075,143
and
-1 x -164,075,143 = 164,075,143
Notice both answers equal 164,075,143
With that explanation out of the way, let's continue. Next, we take the number 164,075,143 and divide it by 2:
164,075,143 ÷ 2 = 82,037,571.5
If the quotient is a whole number, then 2 and 82,037,571.5 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 | 164,075,143 | |
| -1 | -164,075,143 |
Now, we try dividing 164,075,143 by 3:
164,075,143 ÷ 3 = 54,691,714.3333
If the quotient is a whole number, then 3 and 54,691,714.3333 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 | 164,075,143 | |
| -1 | -164,075,143 |
Let's try dividing by 4:
164,075,143 ÷ 4 = 41,018,785.75
If the quotient is a whole number, then 4 and 41,018,785.75 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 | 164,075,143 | |
| -1 | 164,075,143 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 389 | 577 | 731 | 6,613 | 9,809 | 16,727 | 24,811 | 224,453 | 284,359 | 421,787 | 3,815,701 | 9,651,479 | 164,075,143 |
| -1 | -17 | -43 | -389 | -577 | -731 | -6,613 | -9,809 | -16,727 | -24,811 | -224,453 | -284,359 | -421,787 | -3,815,701 | -9,651,479 | -164,075,143 |
