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 74,707,812, 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 | 74,707,812 | |
| -1 | -74,707,812 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,707,812.
Example:
1 x 74,707,812 = 74,707,812
and
-1 x -74,707,812 = 74,707,812
Notice both answers equal 74,707,812
With that explanation out of the way, let's continue. Next, we take the number 74,707,812 and divide it by 2:
74,707,812 ÷ 2 = 37,353,906
If the quotient is a whole number, then 2 and 37,353,906 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 37,353,906 | 74,707,812 | |
| -1 | -2 | -37,353,906 | -74,707,812 |
Now, we try dividing 74,707,812 by 3:
74,707,812 ÷ 3 = 24,902,604
If the quotient is a whole number, then 3 and 24,902,604 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 24,902,604 | 37,353,906 | 74,707,812 | |
| -1 | -2 | -3 | -24,902,604 | -37,353,906 | -74,707,812 |
Let's try dividing by 4:
74,707,812 ÷ 4 = 18,676,953
If the quotient is a whole number, then 4 and 18,676,953 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 18,676,953 | 24,902,604 | 37,353,906 | 74,707,812 | |
| -1 | -2 | -3 | -4 | -18,676,953 | -24,902,604 | -37,353,906 | 74,707,812 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 6 | 9 | 12 | 18 | 27 | 36 | 54 | 108 | 691,739 | 1,383,478 | 2,075,217 | 2,766,956 | 4,150,434 | 6,225,651 | 8,300,868 | 12,451,302 | 18,676,953 | 24,902,604 | 37,353,906 | 74,707,812 |
| -1 | -2 | -3 | -4 | -6 | -9 | -12 | -18 | -27 | -36 | -54 | -108 | -691,739 | -1,383,478 | -2,075,217 | -2,766,956 | -4,150,434 | -6,225,651 | -8,300,868 | -12,451,302 | -18,676,953 | -24,902,604 | -37,353,906 | -74,707,812 |
