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 167,636,575, 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 | 167,636,575 | |
| -1 | -167,636,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,636,575.
Example:
1 x 167,636,575 = 167,636,575
and
-1 x -167,636,575 = 167,636,575
Notice both answers equal 167,636,575
With that explanation out of the way, let's continue. Next, we take the number 167,636,575 and divide it by 2:
167,636,575 ÷ 2 = 83,818,287.5
If the quotient is a whole number, then 2 and 83,818,287.5 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 | 167,636,575 | |
| -1 | -167,636,575 |
Now, we try dividing 167,636,575 by 3:
167,636,575 ÷ 3 = 55,878,858.3333
If the quotient is a whole number, then 3 and 55,878,858.3333 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 | 167,636,575 | |
| -1 | -167,636,575 |
Let's try dividing by 4:
167,636,575 ÷ 4 = 41,909,143.75
If the quotient is a whole number, then 4 and 41,909,143.75 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 | 167,636,575 | |
| -1 | 167,636,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 43 | 85 | 215 | 425 | 731 | 1,075 | 3,655 | 9,173 | 18,275 | 45,865 | 155,941 | 229,325 | 394,439 | 779,705 | 1,972,195 | 3,898,525 | 6,705,463 | 9,860,975 | 33,527,315 | 167,636,575 |
| -1 | -5 | -17 | -25 | -43 | -85 | -215 | -425 | -731 | -1,075 | -3,655 | -9,173 | -18,275 | -45,865 | -155,941 | -229,325 | -394,439 | -779,705 | -1,972,195 | -3,898,525 | -6,705,463 | -9,860,975 | -33,527,315 | -167,636,575 |
