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 37,678,511, 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 | 37,678,511 | |
| -1 | -37,678,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,678,511.
Example:
1 x 37,678,511 = 37,678,511
and
-1 x -37,678,511 = 37,678,511
Notice both answers equal 37,678,511
With that explanation out of the way, let's continue. Next, we take the number 37,678,511 and divide it by 2:
37,678,511 ÷ 2 = 18,839,255.5
If the quotient is a whole number, then 2 and 18,839,255.5 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 | 37,678,511 | |
| -1 | -37,678,511 |
Now, we try dividing 37,678,511 by 3:
37,678,511 ÷ 3 = 12,559,503.6667
If the quotient is a whole number, then 3 and 12,559,503.6667 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 | 37,678,511 | |
| -1 | -37,678,511 |
Let's try dividing by 4:
37,678,511 ÷ 4 = 9,419,627.75
If the quotient is a whole number, then 4 and 9,419,627.75 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 | 37,678,511 | |
| -1 | 37,678,511 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 29 | 221 | 377 | 493 | 5,879 | 6,409 | 76,427 | 99,943 | 170,491 | 1,299,259 | 2,216,383 | 2,898,347 | 37,678,511 |
| -1 | -13 | -17 | -29 | -221 | -377 | -493 | -5,879 | -6,409 | -76,427 | -99,943 | -170,491 | -1,299,259 | -2,216,383 | -2,898,347 | -37,678,511 |
