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 75,663,697, 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 | 75,663,697 | |
| -1 | -75,663,697 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,663,697.
Example:
1 x 75,663,697 = 75,663,697
and
-1 x -75,663,697 = 75,663,697
Notice both answers equal 75,663,697
With that explanation out of the way, let's continue. Next, we take the number 75,663,697 and divide it by 2:
75,663,697 ÷ 2 = 37,831,848.5
If the quotient is a whole number, then 2 and 37,831,848.5 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 | 75,663,697 | |
| -1 | -75,663,697 |
Now, we try dividing 75,663,697 by 3:
75,663,697 ÷ 3 = 25,221,232.3333
If the quotient is a whole number, then 3 and 25,221,232.3333 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 | 75,663,697 | |
| -1 | -75,663,697 |
Let's try dividing by 4:
75,663,697 ÷ 4 = 18,915,924.25
If the quotient is a whole number, then 4 and 18,915,924.25 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 | 75,663,697 | |
| -1 | 75,663,697 |
If you did it right, you will end up with this table:
| 1 | 29 | 73 | 103 | 347 | 2,117 | 2,987 | 7,519 | 10,063 | 25,331 | 35,741 | 218,051 | 734,599 | 1,036,489 | 2,609,093 | 75,663,697 |
| -1 | -29 | -73 | -103 | -347 | -2,117 | -2,987 | -7,519 | -10,063 | -25,331 | -35,741 | -218,051 | -734,599 | -1,036,489 | -2,609,093 | -75,663,697 |
