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 74,476,031, 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 | 74,476,031 | |
| -1 | -74,476,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,476,031.
Example:
1 x 74,476,031 = 74,476,031
and
-1 x -74,476,031 = 74,476,031
Notice both answers equal 74,476,031
With that explanation out of the way, let's continue. Next, we take the number 74,476,031 and divide it by 2:
74,476,031 ÷ 2 = 37,238,015.5
If the quotient is a whole number, then 2 and 37,238,015.5 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 | 74,476,031 | |
| -1 | -74,476,031 |
Now, we try dividing 74,476,031 by 3:
74,476,031 ÷ 3 = 24,825,343.6667
If the quotient is a whole number, then 3 and 24,825,343.6667 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 | 74,476,031 | |
| -1 | -74,476,031 |
Let's try dividing by 4:
74,476,031 ÷ 4 = 18,619,007.75
If the quotient is a whole number, then 4 and 18,619,007.75 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 | 74,476,031 | |
| -1 | 74,476,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 29 | 49 | 119 | 203 | 493 | 833 | 1,421 | 3,083 | 3,451 | 21,581 | 24,157 | 52,411 | 89,407 | 151,067 | 366,877 | 625,849 | 1,519,919 | 2,568,139 | 4,380,943 | 10,639,433 | 74,476,031 |
| -1 | -7 | -17 | -29 | -49 | -119 | -203 | -493 | -833 | -1,421 | -3,083 | -3,451 | -21,581 | -24,157 | -52,411 | -89,407 | -151,067 | -366,877 | -625,849 | -1,519,919 | -2,568,139 | -4,380,943 | -10,639,433 | -74,476,031 |
