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 74,070,337, 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 | 74,070,337 | |
| -1 | -74,070,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,070,337.
Example:
1 x 74,070,337 = 74,070,337
and
-1 x -74,070,337 = 74,070,337
Notice both answers equal 74,070,337
With that explanation out of the way, let's continue. Next, we take the number 74,070,337 and divide it by 2:
74,070,337 ÷ 2 = 37,035,168.5
If the quotient is a whole number, then 2 and 37,035,168.5 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 | 74,070,337 | |
| -1 | -74,070,337 |
Now, we try dividing 74,070,337 by 3:
74,070,337 ÷ 3 = 24,690,112.3333
If the quotient is a whole number, then 3 and 24,690,112.3333 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 | 74,070,337 | |
| -1 | -74,070,337 |
Let's try dividing by 4:
74,070,337 ÷ 4 = 18,517,584.25
If the quotient is a whole number, then 4 and 18,517,584.25 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 | 74,070,337 | |
| -1 | 74,070,337 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 127 | 407 | 1,397 | 1,433 | 4,699 | 15,763 | 51,689 | 53,021 | 181,991 | 583,231 | 2,001,901 | 6,733,667 | 74,070,337 |
| -1 | -11 | -37 | -127 | -407 | -1,397 | -1,433 | -4,699 | -15,763 | -51,689 | -53,021 | -181,991 | -583,231 | -2,001,901 | -6,733,667 | -74,070,337 |
