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 74,039,105, 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 | 74,039,105 | |
| -1 | -74,039,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,039,105.
Example:
1 x 74,039,105 = 74,039,105
and
-1 x -74,039,105 = 74,039,105
Notice both answers equal 74,039,105
With that explanation out of the way, let's continue. Next, we take the number 74,039,105 and divide it by 2:
74,039,105 ÷ 2 = 37,019,552.5
If the quotient is a whole number, then 2 and 37,019,552.5 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 | 74,039,105 | |
| -1 | -74,039,105 |
Now, we try dividing 74,039,105 by 3:
74,039,105 ÷ 3 = 24,679,701.6667
If the quotient is a whole number, then 3 and 24,679,701.6667 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 | 74,039,105 | |
| -1 | -74,039,105 |
Let's try dividing by 4:
74,039,105 ÷ 4 = 18,509,776.25
If the quotient is a whole number, then 4 and 18,509,776.25 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 | 74,039,105 | |
| -1 | 74,039,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 111,337 | 556,685 | 779,359 | 2,115,403 | 3,896,795 | 10,577,015 | 14,807,821 | 74,039,105 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -111,337 | -556,685 | -779,359 | -2,115,403 | -3,896,795 | -10,577,015 | -14,807,821 | -74,039,105 |
