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 37,679,845, 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 | 37,679,845 | |
| -1 | -37,679,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,679,845.
Example:
1 x 37,679,845 = 37,679,845
and
-1 x -37,679,845 = 37,679,845
Notice both answers equal 37,679,845
With that explanation out of the way, let's continue. Next, we take the number 37,679,845 and divide it by 2:
37,679,845 ÷ 2 = 18,839,922.5
If the quotient is a whole number, then 2 and 18,839,922.5 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 | 37,679,845 | |
| -1 | -37,679,845 |
Now, we try dividing 37,679,845 by 3:
37,679,845 ÷ 3 = 12,559,948.3333
If the quotient is a whole number, then 3 and 12,559,948.3333 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 | 37,679,845 | |
| -1 | -37,679,845 |
Let's try dividing by 4:
37,679,845 ÷ 4 = 9,419,961.25
If the quotient is a whole number, then 4 and 9,419,961.25 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 | 37,679,845 | |
| -1 | 37,679,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 37,123 | 185,615 | 259,861 | 1,076,567 | 1,299,305 | 5,382,835 | 7,535,969 | 37,679,845 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -37,123 | -185,615 | -259,861 | -1,076,567 | -1,299,305 | -5,382,835 | -7,535,969 | -37,679,845 |
