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 127,326,073, 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 | 127,326,073 | |
| -1 | -127,326,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 127,326,073.
Example:
1 x 127,326,073 = 127,326,073
and
-1 x -127,326,073 = 127,326,073
Notice both answers equal 127,326,073
With that explanation out of the way, let's continue. Next, we take the number 127,326,073 and divide it by 2:
127,326,073 ÷ 2 = 63,663,036.5
If the quotient is a whole number, then 2 and 63,663,036.5 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 | 127,326,073 | |
| -1 | -127,326,073 |
Now, we try dividing 127,326,073 by 3:
127,326,073 ÷ 3 = 42,442,024.3333
If the quotient is a whole number, then 3 and 42,442,024.3333 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 | 127,326,073 | |
| -1 | -127,326,073 |
Let's try dividing by 4:
127,326,073 ÷ 4 = 31,831,518.25
If the quotient is a whole number, then 4 and 31,831,518.25 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 | 127,326,073 | |
| -1 | 127,326,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 449 | 2,383 | 3,143 | 7,633 | 16,681 | 40,511 | 53,431 | 283,577 | 1,069,967 | 7,489,769 | 18,189,439 | 127,326,073 |
| -1 | -7 | -17 | -119 | -449 | -2,383 | -3,143 | -7,633 | -16,681 | -40,511 | -53,431 | -283,577 | -1,069,967 | -7,489,769 | -18,189,439 | -127,326,073 |
