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 177,415,175, 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 | 177,415,175 | |
| -1 | -177,415,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,415,175.
Example:
1 x 177,415,175 = 177,415,175
and
-1 x -177,415,175 = 177,415,175
Notice both answers equal 177,415,175
With that explanation out of the way, let's continue. Next, we take the number 177,415,175 and divide it by 2:
177,415,175 ÷ 2 = 88,707,587.5
If the quotient is a whole number, then 2 and 88,707,587.5 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 | 177,415,175 | |
| -1 | -177,415,175 |
Now, we try dividing 177,415,175 by 3:
177,415,175 ÷ 3 = 59,138,391.6667
If the quotient is a whole number, then 3 and 59,138,391.6667 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 | 177,415,175 | |
| -1 | -177,415,175 |
Let's try dividing by 4:
177,415,175 ÷ 4 = 44,353,793.75
If the quotient is a whole number, then 4 and 44,353,793.75 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 | 177,415,175 | |
| -1 | 177,415,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 383 | 1,915 | 2,647 | 2,681 | 9,575 | 13,235 | 13,405 | 18,529 | 66,175 | 67,025 | 92,645 | 463,225 | 1,013,801 | 5,069,005 | 7,096,607 | 25,345,025 | 35,483,035 | 177,415,175 |
| -1 | -5 | -7 | -25 | -35 | -175 | -383 | -1,915 | -2,647 | -2,681 | -9,575 | -13,235 | -13,405 | -18,529 | -66,175 | -67,025 | -92,645 | -463,225 | -1,013,801 | -5,069,005 | -7,096,607 | -25,345,025 | -35,483,035 | -177,415,175 |
