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 74,011,783, 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 | 74,011,783 | |
| -1 | -74,011,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,011,783.
Example:
1 x 74,011,783 = 74,011,783
and
-1 x -74,011,783 = 74,011,783
Notice both answers equal 74,011,783
With that explanation out of the way, let's continue. Next, we take the number 74,011,783 and divide it by 2:
74,011,783 ÷ 2 = 37,005,891.5
If the quotient is a whole number, then 2 and 37,005,891.5 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 | 74,011,783 | |
| -1 | -74,011,783 |
Now, we try dividing 74,011,783 by 3:
74,011,783 ÷ 3 = 24,670,594.3333
If the quotient is a whole number, then 3 and 24,670,594.3333 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 | 74,011,783 | |
| -1 | -74,011,783 |
Let's try dividing by 4:
74,011,783 ÷ 4 = 18,502,945.75
If the quotient is a whole number, then 4 and 18,502,945.75 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 | 74,011,783 | |
| -1 | 74,011,783 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 103 | 641 | 1,121 | 1,957 | 6,077 | 12,179 | 37,819 | 66,023 | 115,463 | 718,561 | 1,254,437 | 3,895,357 | 74,011,783 |
| -1 | -19 | -59 | -103 | -641 | -1,121 | -1,957 | -6,077 | -12,179 | -37,819 | -66,023 | -115,463 | -718,561 | -1,254,437 | -3,895,357 | -74,011,783 |
