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 177,070,375, 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 | 177,070,375 | |
| -1 | -177,070,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,070,375.
Example:
1 x 177,070,375 = 177,070,375
and
-1 x -177,070,375 = 177,070,375
Notice both answers equal 177,070,375
With that explanation out of the way, let's continue. Next, we take the number 177,070,375 and divide it by 2:
177,070,375 ÷ 2 = 88,535,187.5
If the quotient is a whole number, then 2 and 88,535,187.5 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 | 177,070,375 | |
| -1 | -177,070,375 |
Now, we try dividing 177,070,375 by 3:
177,070,375 ÷ 3 = 59,023,458.3333
If the quotient is a whole number, then 3 and 59,023,458.3333 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 | 177,070,375 | |
| -1 | -177,070,375 |
Let's try dividing by 4:
177,070,375 ÷ 4 = 44,267,593.75
If the quotient is a whole number, then 4 and 44,267,593.75 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 | 177,070,375 | |
| -1 | 177,070,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 125 | 145 | 725 | 3,625 | 48,847 | 244,235 | 1,221,175 | 1,416,563 | 6,105,875 | 7,082,815 | 35,414,075 | 177,070,375 |
| -1 | -5 | -25 | -29 | -125 | -145 | -725 | -3,625 | -48,847 | -244,235 | -1,221,175 | -1,416,563 | -6,105,875 | -7,082,815 | -35,414,075 | -177,070,375 |
