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 37,670,171, 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 | 37,670,171 | |
| -1 | -37,670,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,670,171.
Example:
1 x 37,670,171 = 37,670,171
and
-1 x -37,670,171 = 37,670,171
Notice both answers equal 37,670,171
With that explanation out of the way, let's continue. Next, we take the number 37,670,171 and divide it by 2:
37,670,171 ÷ 2 = 18,835,085.5
If the quotient is a whole number, then 2 and 18,835,085.5 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 | 37,670,171 | |
| -1 | -37,670,171 |
Now, we try dividing 37,670,171 by 3:
37,670,171 ÷ 3 = 12,556,723.6667
If the quotient is a whole number, then 3 and 12,556,723.6667 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 | 37,670,171 | |
| -1 | -37,670,171 |
Let's try dividing by 4:
37,670,171 ÷ 4 = 9,417,542.75
If the quotient is a whole number, then 4 and 9,417,542.75 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 | 37,670,171 | |
| -1 | 37,670,171 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 49 | 77 | 329 | 517 | 539 | 1,487 | 2,303 | 3,619 | 10,409 | 16,357 | 25,333 | 69,889 | 72,863 | 114,499 | 489,223 | 768,779 | 801,493 | 3,424,561 | 5,381,453 | 37,670,171 |
| -1 | -7 | -11 | -47 | -49 | -77 | -329 | -517 | -539 | -1,487 | -2,303 | -3,619 | -10,409 | -16,357 | -25,333 | -69,889 | -72,863 | -114,499 | -489,223 | -768,779 | -801,493 | -3,424,561 | -5,381,453 | -37,670,171 |
