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 172,140,763, 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 | 172,140,763 | |
| -1 | -172,140,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,140,763.
Example:
1 x 172,140,763 = 172,140,763
and
-1 x -172,140,763 = 172,140,763
Notice both answers equal 172,140,763
With that explanation out of the way, let's continue. Next, we take the number 172,140,763 and divide it by 2:
172,140,763 ÷ 2 = 86,070,381.5
If the quotient is a whole number, then 2 and 86,070,381.5 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 | 172,140,763 | |
| -1 | -172,140,763 |
Now, we try dividing 172,140,763 by 3:
172,140,763 ÷ 3 = 57,380,254.3333
If the quotient is a whole number, then 3 and 57,380,254.3333 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 | 172,140,763 | |
| -1 | -172,140,763 |
Let's try dividing by 4:
172,140,763 ÷ 4 = 43,035,190.75
If the quotient is a whole number, then 4 and 43,035,190.75 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 | 172,140,763 | |
| -1 | 172,140,763 |
If you did it right, you will end up with this table:
| 1 | 23 | 79 | 211 | 449 | 1,817 | 4,853 | 10,327 | 16,669 | 35,471 | 94,739 | 383,387 | 815,833 | 2,178,997 | 7,484,381 | 172,140,763 |
| -1 | -23 | -79 | -211 | -449 | -1,817 | -4,853 | -10,327 | -16,669 | -35,471 | -94,739 | -383,387 | -815,833 | -2,178,997 | -7,484,381 | -172,140,763 |
