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 13,722,175, 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 | 13,722,175 | |
| -1 | -13,722,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,722,175.
Example:
1 x 13,722,175 = 13,722,175
and
-1 x -13,722,175 = 13,722,175
Notice both answers equal 13,722,175
With that explanation out of the way, let's continue. Next, we take the number 13,722,175 and divide it by 2:
13,722,175 ÷ 2 = 6,861,087.5
If the quotient is a whole number, then 2 and 6,861,087.5 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 | 13,722,175 | |
| -1 | -13,722,175 |
Now, we try dividing 13,722,175 by 3:
13,722,175 ÷ 3 = 4,574,058.3333
If the quotient is a whole number, then 3 and 4,574,058.3333 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 | 13,722,175 | |
| -1 | -13,722,175 |
Let's try dividing by 4:
13,722,175 ÷ 4 = 3,430,543.75
If the quotient is a whole number, then 4 and 3,430,543.75 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 | 13,722,175 | |
| -1 | 13,722,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 73 | 103 | 365 | 515 | 1,825 | 2,575 | 5,329 | 7,519 | 26,645 | 37,595 | 133,225 | 187,975 | 548,887 | 2,744,435 | 13,722,175 |
| -1 | -5 | -25 | -73 | -103 | -365 | -515 | -1,825 | -2,575 | -5,329 | -7,519 | -26,645 | -37,595 | -133,225 | -187,975 | -548,887 | -2,744,435 | -13,722,175 |
