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 74,008,535, 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 | 74,008,535 | |
| -1 | -74,008,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,008,535.
Example:
1 x 74,008,535 = 74,008,535
and
-1 x -74,008,535 = 74,008,535
Notice both answers equal 74,008,535
With that explanation out of the way, let's continue. Next, we take the number 74,008,535 and divide it by 2:
74,008,535 ÷ 2 = 37,004,267.5
If the quotient is a whole number, then 2 and 37,004,267.5 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 | 74,008,535 | |
| -1 | -74,008,535 |
Now, we try dividing 74,008,535 by 3:
74,008,535 ÷ 3 = 24,669,511.6667
If the quotient is a whole number, then 3 and 24,669,511.6667 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 | 74,008,535 | |
| -1 | -74,008,535 |
Let's try dividing by 4:
74,008,535 ÷ 4 = 18,502,133.75
If the quotient is a whole number, then 4 and 18,502,133.75 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 | 74,008,535 | |
| -1 | 74,008,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 173 | 335 | 865 | 1,277 | 6,385 | 11,591 | 57,955 | 85,559 | 220,921 | 427,795 | 1,104,605 | 14,801,707 | 74,008,535 |
| -1 | -5 | -67 | -173 | -335 | -865 | -1,277 | -6,385 | -11,591 | -57,955 | -85,559 | -220,921 | -427,795 | -1,104,605 | -14,801,707 | -74,008,535 |
