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 175,177,415, 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 | 175,177,415 | |
| -1 | -175,177,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 175,177,415.
Example:
1 x 175,177,415 = 175,177,415
and
-1 x -175,177,415 = 175,177,415
Notice both answers equal 175,177,415
With that explanation out of the way, let's continue. Next, we take the number 175,177,415 and divide it by 2:
175,177,415 ÷ 2 = 87,588,707.5
If the quotient is a whole number, then 2 and 87,588,707.5 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 | 175,177,415 | |
| -1 | -175,177,415 |
Now, we try dividing 175,177,415 by 3:
175,177,415 ÷ 3 = 58,392,471.6667
If the quotient is a whole number, then 3 and 58,392,471.6667 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 | 175,177,415 | |
| -1 | -175,177,415 |
Let's try dividing by 4:
175,177,415 ÷ 4 = 43,794,353.75
If the quotient is a whole number, then 4 and 43,794,353.75 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 | 175,177,415 | |
| -1 | 175,177,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 193 | 965 | 1,351 | 6,755 | 25,933 | 129,665 | 181,531 | 907,655 | 5,005,069 | 25,025,345 | 35,035,483 | 175,177,415 |
| -1 | -5 | -7 | -35 | -193 | -965 | -1,351 | -6,755 | -25,933 | -129,665 | -181,531 | -907,655 | -5,005,069 | -25,025,345 | -35,035,483 | -175,177,415 |
