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 75,066,761, 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 | 75,066,761 | |
| -1 | -75,066,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,066,761.
Example:
1 x 75,066,761 = 75,066,761
and
-1 x -75,066,761 = 75,066,761
Notice both answers equal 75,066,761
With that explanation out of the way, let's continue. Next, we take the number 75,066,761 and divide it by 2:
75,066,761 ÷ 2 = 37,533,380.5
If the quotient is a whole number, then 2 and 37,533,380.5 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 | 75,066,761 | |
| -1 | -75,066,761 |
Now, we try dividing 75,066,761 by 3:
75,066,761 ÷ 3 = 25,022,253.6667
If the quotient is a whole number, then 3 and 25,022,253.6667 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 | 75,066,761 | |
| -1 | -75,066,761 |
Let's try dividing by 4:
75,066,761 ÷ 4 = 18,766,690.25
If the quotient is a whole number, then 4 and 18,766,690.25 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 | 75,066,761 | |
| -1 | 75,066,761 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 33,617 | 235,319 | 369,787 | 974,893 | 2,588,509 | 6,824,251 | 10,723,823 | 75,066,761 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -33,617 | -235,319 | -369,787 | -974,893 | -2,588,509 | -6,824,251 | -10,723,823 | -75,066,761 |
