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 37,866,961, 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 | 37,866,961 | |
| -1 | -37,866,961 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,866,961.
Example:
1 x 37,866,961 = 37,866,961
and
-1 x -37,866,961 = 37,866,961
Notice both answers equal 37,866,961
With that explanation out of the way, let's continue. Next, we take the number 37,866,961 and divide it by 2:
37,866,961 ÷ 2 = 18,933,480.5
If the quotient is a whole number, then 2 and 18,933,480.5 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 | 37,866,961 | |
| -1 | -37,866,961 |
Now, we try dividing 37,866,961 by 3:
37,866,961 ÷ 3 = 12,622,320.3333
If the quotient is a whole number, then 3 and 12,622,320.3333 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 | 37,866,961 | |
| -1 | -37,866,961 |
Let's try dividing by 4:
37,866,961 ÷ 4 = 9,466,740.25
If the quotient is a whole number, then 4 and 9,466,740.25 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 | 37,866,961 | |
| -1 | 37,866,961 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 223 | 359 | 473 | 2,453 | 3,949 | 9,589 | 15,437 | 80,057 | 105,479 | 169,807 | 880,627 | 3,442,451 | 37,866,961 |
| -1 | -11 | -43 | -223 | -359 | -473 | -2,453 | -3,949 | -9,589 | -15,437 | -80,057 | -105,479 | -169,807 | -880,627 | -3,442,451 | -37,866,961 |
