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 175,277,123, 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 | 175,277,123 | |
| -1 | -175,277,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 175,277,123.
Example:
1 x 175,277,123 = 175,277,123
and
-1 x -175,277,123 = 175,277,123
Notice both answers equal 175,277,123
With that explanation out of the way, let's continue. Next, we take the number 175,277,123 and divide it by 2:
175,277,123 ÷ 2 = 87,638,561.5
If the quotient is a whole number, then 2 and 87,638,561.5 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 | 175,277,123 | |
| -1 | -175,277,123 |
Now, we try dividing 175,277,123 by 3:
175,277,123 ÷ 3 = 58,425,707.6667
If the quotient is a whole number, then 3 and 58,425,707.6667 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 | 175,277,123 | |
| -1 | -175,277,123 |
Let's try dividing by 4:
175,277,123 ÷ 4 = 43,819,280.75
If the quotient is a whole number, then 4 and 43,819,280.75 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 | 175,277,123 | |
| -1 | 175,277,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 109 | 119 | 763 | 1,853 | 12,971 | 13,513 | 94,591 | 229,721 | 1,472,917 | 1,608,047 | 10,310,419 | 25,039,589 | 175,277,123 |
| -1 | -7 | -17 | -109 | -119 | -763 | -1,853 | -12,971 | -13,513 | -94,591 | -229,721 | -1,472,917 | -1,608,047 | -10,310,419 | -25,039,589 | -175,277,123 |
