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 37,515,823, 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 | 37,515,823 | |
| -1 | -37,515,823 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,515,823.
Example:
1 x 37,515,823 = 37,515,823
and
-1 x -37,515,823 = 37,515,823
Notice both answers equal 37,515,823
With that explanation out of the way, let's continue. Next, we take the number 37,515,823 and divide it by 2:
37,515,823 ÷ 2 = 18,757,911.5
If the quotient is a whole number, then 2 and 18,757,911.5 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 | 37,515,823 | |
| -1 | -37,515,823 |
Now, we try dividing 37,515,823 by 3:
37,515,823 ÷ 3 = 12,505,274.3333
If the quotient is a whole number, then 3 and 12,505,274.3333 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 | 37,515,823 | |
| -1 | -37,515,823 |
Let's try dividing by 4:
37,515,823 ÷ 4 = 9,378,955.75
If the quotient is a whole number, then 4 and 9,378,955.75 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 | 37,515,823 | |
| -1 | 37,515,823 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 47 | 817 | 893 | 977 | 2,021 | 18,563 | 38,399 | 42,011 | 45,919 | 798,209 | 872,461 | 1,974,517 | 37,515,823 |
| -1 | -19 | -43 | -47 | -817 | -893 | -977 | -2,021 | -18,563 | -38,399 | -42,011 | -45,919 | -798,209 | -872,461 | -1,974,517 | -37,515,823 |
