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 75,632,537, 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 | 75,632,537 | |
| -1 | -75,632,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,632,537.
Example:
1 x 75,632,537 = 75,632,537
and
-1 x -75,632,537 = 75,632,537
Notice both answers equal 75,632,537
With that explanation out of the way, let's continue. Next, we take the number 75,632,537 and divide it by 2:
75,632,537 ÷ 2 = 37,816,268.5
If the quotient is a whole number, then 2 and 37,816,268.5 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 | 75,632,537 | |
| -1 | -75,632,537 |
Now, we try dividing 75,632,537 by 3:
75,632,537 ÷ 3 = 25,210,845.6667
If the quotient is a whole number, then 3 and 25,210,845.6667 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 | 75,632,537 | |
| -1 | -75,632,537 |
Let's try dividing by 4:
75,632,537 ÷ 4 = 18,908,134.25
If the quotient is a whole number, then 4 and 18,908,134.25 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 | 75,632,537 | |
| -1 | 75,632,537 |
If you did it right, you will end up with this table:
| 1 | 53 | 71 | 101 | 199 | 3,763 | 5,353 | 7,171 | 10,547 | 14,129 | 20,099 | 380,063 | 748,837 | 1,065,247 | 1,427,029 | 75,632,537 |
| -1 | -53 | -71 | -101 | -199 | -3,763 | -5,353 | -7,171 | -10,547 | -14,129 | -20,099 | -380,063 | -748,837 | -1,065,247 | -1,427,029 | -75,632,537 |
