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 74,744,455, 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 | 74,744,455 | |
| -1 | -74,744,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,744,455.
Example:
1 x 74,744,455 = 74,744,455
and
-1 x -74,744,455 = 74,744,455
Notice both answers equal 74,744,455
With that explanation out of the way, let's continue. Next, we take the number 74,744,455 and divide it by 2:
74,744,455 ÷ 2 = 37,372,227.5
If the quotient is a whole number, then 2 and 37,372,227.5 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 | 74,744,455 | |
| -1 | -74,744,455 |
Now, we try dividing 74,744,455 by 3:
74,744,455 ÷ 3 = 24,914,818.3333
If the quotient is a whole number, then 3 and 24,914,818.3333 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 | 74,744,455 | |
| -1 | -74,744,455 |
Let's try dividing by 4:
74,744,455 ÷ 4 = 18,686,113.75
If the quotient is a whole number, then 4 and 18,686,113.75 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 | 74,744,455 | |
| -1 | 74,744,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 229 | 1,145 | 2,251 | 6,641 | 11,255 | 33,205 | 65,279 | 326,395 | 515,479 | 2,577,395 | 14,948,891 | 74,744,455 |
| -1 | -5 | -29 | -145 | -229 | -1,145 | -2,251 | -6,641 | -11,255 | -33,205 | -65,279 | -326,395 | -515,479 | -2,577,395 | -14,948,891 | -74,744,455 |
