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 172,060,631, 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 | 172,060,631 | |
| -1 | -172,060,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,060,631.
Example:
1 x 172,060,631 = 172,060,631
and
-1 x -172,060,631 = 172,060,631
Notice both answers equal 172,060,631
With that explanation out of the way, let's continue. Next, we take the number 172,060,631 and divide it by 2:
172,060,631 ÷ 2 = 86,030,315.5
If the quotient is a whole number, then 2 and 86,030,315.5 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 | 172,060,631 | |
| -1 | -172,060,631 |
Now, we try dividing 172,060,631 by 3:
172,060,631 ÷ 3 = 57,353,543.6667
If the quotient is a whole number, then 3 and 57,353,543.6667 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 | 172,060,631 | |
| -1 | -172,060,631 |
Let's try dividing by 4:
172,060,631 ÷ 4 = 43,015,157.75
If the quotient is a whole number, then 4 and 43,015,157.75 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 | 172,060,631 | |
| -1 | 172,060,631 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 191 | 739 | 1,219 | 4,393 | 10,123 | 16,997 | 39,167 | 141,149 | 232,829 | 900,841 | 3,246,427 | 7,480,897 | 172,060,631 |
| -1 | -23 | -53 | -191 | -739 | -1,219 | -4,393 | -10,123 | -16,997 | -39,167 | -141,149 | -232,829 | -900,841 | -3,246,427 | -7,480,897 | -172,060,631 |
