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 74,483,815, 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 | 74,483,815 | |
| -1 | -74,483,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,483,815.
Example:
1 x 74,483,815 = 74,483,815
and
-1 x -74,483,815 = 74,483,815
Notice both answers equal 74,483,815
With that explanation out of the way, let's continue. Next, we take the number 74,483,815 and divide it by 2:
74,483,815 ÷ 2 = 37,241,907.5
If the quotient is a whole number, then 2 and 37,241,907.5 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 | 74,483,815 | |
| -1 | -74,483,815 |
Now, we try dividing 74,483,815 by 3:
74,483,815 ÷ 3 = 24,827,938.3333
If the quotient is a whole number, then 3 and 24,827,938.3333 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 | 74,483,815 | |
| -1 | -74,483,815 |
Let's try dividing by 4:
74,483,815 ÷ 4 = 18,620,953.75
If the quotient is a whole number, then 4 and 18,620,953.75 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 | 74,483,815 | |
| -1 | 74,483,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 40,153 | 200,765 | 281,071 | 1,405,355 | 2,128,109 | 10,640,545 | 14,896,763 | 74,483,815 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -40,153 | -200,765 | -281,071 | -1,405,355 | -2,128,109 | -10,640,545 | -14,896,763 | -74,483,815 |
