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 75,674,027, 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 | 75,674,027 | |
| -1 | -75,674,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,674,027.
Example:
1 x 75,674,027 = 75,674,027
and
-1 x -75,674,027 = 75,674,027
Notice both answers equal 75,674,027
With that explanation out of the way, let's continue. Next, we take the number 75,674,027 and divide it by 2:
75,674,027 ÷ 2 = 37,837,013.5
If the quotient is a whole number, then 2 and 37,837,013.5 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 | 75,674,027 | |
| -1 | -75,674,027 |
Now, we try dividing 75,674,027 by 3:
75,674,027 ÷ 3 = 25,224,675.6667
If the quotient is a whole number, then 3 and 25,224,675.6667 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 | 75,674,027 | |
| -1 | -75,674,027 |
Let's try dividing by 4:
75,674,027 ÷ 4 = 18,918,506.75
If the quotient is a whole number, then 4 and 18,918,506.75 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 | 75,674,027 | |
| -1 | 75,674,027 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 643 | 823 | 7,073 | 8,359 | 9,053 | 10,699 | 91,949 | 117,689 | 529,189 | 5,821,079 | 6,879,457 | 75,674,027 |
| -1 | -11 | -13 | -143 | -643 | -823 | -7,073 | -8,359 | -9,053 | -10,699 | -91,949 | -117,689 | -529,189 | -5,821,079 | -6,879,457 | -75,674,027 |
