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 171,052,525, 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 | 171,052,525 | |
| -1 | -171,052,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,052,525.
Example:
1 x 171,052,525 = 171,052,525
and
-1 x -171,052,525 = 171,052,525
Notice both answers equal 171,052,525
With that explanation out of the way, let's continue. Next, we take the number 171,052,525 and divide it by 2:
171,052,525 ÷ 2 = 85,526,262.5
If the quotient is a whole number, then 2 and 85,526,262.5 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 | 171,052,525 | |
| -1 | -171,052,525 |
Now, we try dividing 171,052,525 by 3:
171,052,525 ÷ 3 = 57,017,508.3333
If the quotient is a whole number, then 3 and 57,017,508.3333 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 | 171,052,525 | |
| -1 | -171,052,525 |
Let's try dividing by 4:
171,052,525 ÷ 4 = 42,763,131.25
If the quotient is a whole number, then 4 and 42,763,131.25 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 | 171,052,525 | |
| -1 | 171,052,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 331 | 1,655 | 2,317 | 2,953 | 8,275 | 11,585 | 14,765 | 20,671 | 57,925 | 73,825 | 103,355 | 516,775 | 977,443 | 4,887,215 | 6,842,101 | 24,436,075 | 34,210,505 | 171,052,525 |
| -1 | -5 | -7 | -25 | -35 | -175 | -331 | -1,655 | -2,317 | -2,953 | -8,275 | -11,585 | -14,765 | -20,671 | -57,925 | -73,825 | -103,355 | -516,775 | -977,443 | -4,887,215 | -6,842,101 | -24,436,075 | -34,210,505 | -171,052,525 |
