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 167,531,075, 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 | 167,531,075 | |
| -1 | -167,531,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,531,075.
Example:
1 x 167,531,075 = 167,531,075
and
-1 x -167,531,075 = 167,531,075
Notice both answers equal 167,531,075
With that explanation out of the way, let's continue. Next, we take the number 167,531,075 and divide it by 2:
167,531,075 ÷ 2 = 83,765,537.5
If the quotient is a whole number, then 2 and 83,765,537.5 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 | 167,531,075 | |
| -1 | -167,531,075 |
Now, we try dividing 167,531,075 by 3:
167,531,075 ÷ 3 = 55,843,691.6667
If the quotient is a whole number, then 3 and 55,843,691.6667 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 | 167,531,075 | |
| -1 | -167,531,075 |
Let's try dividing by 4:
167,531,075 ÷ 4 = 41,882,768.75
If the quotient is a whole number, then 4 and 41,882,768.75 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 | 167,531,075 | |
| -1 | 167,531,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 361 | 475 | 977 | 1,805 | 4,885 | 6,859 | 9,025 | 18,563 | 24,425 | 34,295 | 92,815 | 171,475 | 352,697 | 464,075 | 1,763,485 | 6,701,243 | 8,817,425 | 33,506,215 | 167,531,075 |
| -1 | -5 | -19 | -25 | -95 | -361 | -475 | -977 | -1,805 | -4,885 | -6,859 | -9,025 | -18,563 | -24,425 | -34,295 | -92,815 | -171,475 | -352,697 | -464,075 | -1,763,485 | -6,701,243 | -8,817,425 | -33,506,215 | -167,531,075 |
