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 177,150,265, 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 | 177,150,265 | |
| -1 | -177,150,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,150,265.
Example:
1 x 177,150,265 = 177,150,265
and
-1 x -177,150,265 = 177,150,265
Notice both answers equal 177,150,265
With that explanation out of the way, let's continue. Next, we take the number 177,150,265 and divide it by 2:
177,150,265 ÷ 2 = 88,575,132.5
If the quotient is a whole number, then 2 and 88,575,132.5 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 | 177,150,265 | |
| -1 | -177,150,265 |
Now, we try dividing 177,150,265 by 3:
177,150,265 ÷ 3 = 59,050,088.3333
If the quotient is a whole number, then 3 and 59,050,088.3333 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 | 177,150,265 | |
| -1 | -177,150,265 |
Let's try dividing by 4:
177,150,265 ÷ 4 = 44,287,566.25
If the quotient is a whole number, then 4 and 44,287,566.25 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 | 177,150,265 | |
| -1 | 177,150,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 311 | 1,555 | 3,079 | 11,507 | 15,395 | 57,535 | 113,923 | 569,615 | 957,569 | 4,787,845 | 35,430,053 | 177,150,265 |
| -1 | -5 | -37 | -185 | -311 | -1,555 | -3,079 | -11,507 | -15,395 | -57,535 | -113,923 | -569,615 | -957,569 | -4,787,845 | -35,430,053 | -177,150,265 |
