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 36,890,357, 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 | 36,890,357 | |
| -1 | -36,890,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,890,357.
Example:
1 x 36,890,357 = 36,890,357
and
-1 x -36,890,357 = 36,890,357
Notice both answers equal 36,890,357
With that explanation out of the way, let's continue. Next, we take the number 36,890,357 and divide it by 2:
36,890,357 ÷ 2 = 18,445,178.5
If the quotient is a whole number, then 2 and 18,445,178.5 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 | 36,890,357 | |
| -1 | -36,890,357 |
Now, we try dividing 36,890,357 by 3:
36,890,357 ÷ 3 = 12,296,785.6667
If the quotient is a whole number, then 3 and 12,296,785.6667 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 | 36,890,357 | |
| -1 | -36,890,357 |
Let's try dividing by 4:
36,890,357 ÷ 4 = 9,222,589.25
If the quotient is a whole number, then 4 and 9,222,589.25 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 | 36,890,357 | |
| -1 | 36,890,357 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 151 | 1,057 | 2,053 | 2,567 | 14,371 | 17,969 | 34,901 | 244,307 | 310,003 | 2,170,021 | 5,270,051 | 36,890,357 |
| -1 | -7 | -17 | -119 | -151 | -1,057 | -2,053 | -2,567 | -14,371 | -17,969 | -34,901 | -244,307 | -310,003 | -2,170,021 | -5,270,051 | -36,890,357 |
