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 74,284,835, 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 | 74,284,835 | |
| -1 | -74,284,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,284,835.
Example:
1 x 74,284,835 = 74,284,835
and
-1 x -74,284,835 = 74,284,835
Notice both answers equal 74,284,835
With that explanation out of the way, let's continue. Next, we take the number 74,284,835 and divide it by 2:
74,284,835 ÷ 2 = 37,142,417.5
If the quotient is a whole number, then 2 and 37,142,417.5 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 | 74,284,835 | |
| -1 | -74,284,835 |
Now, we try dividing 74,284,835 by 3:
74,284,835 ÷ 3 = 24,761,611.6667
If the quotient is a whole number, then 3 and 24,761,611.6667 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 | 74,284,835 | |
| -1 | -74,284,835 |
Let's try dividing by 4:
74,284,835 ÷ 4 = 18,571,208.75
If the quotient is a whole number, then 4 and 18,571,208.75 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 | 74,284,835 | |
| -1 | 74,284,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 59 | 155 | 295 | 1,829 | 8,123 | 9,145 | 40,615 | 251,813 | 479,257 | 1,259,065 | 2,396,285 | 14,856,967 | 74,284,835 |
| -1 | -5 | -31 | -59 | -155 | -295 | -1,829 | -8,123 | -9,145 | -40,615 | -251,813 | -479,257 | -1,259,065 | -2,396,285 | -14,856,967 | -74,284,835 |
