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 36,889,259, 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 | 36,889,259 | |
| -1 | -36,889,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,889,259.
Example:
1 x 36,889,259 = 36,889,259
and
-1 x -36,889,259 = 36,889,259
Notice both answers equal 36,889,259
With that explanation out of the way, let's continue. Next, we take the number 36,889,259 and divide it by 2:
36,889,259 ÷ 2 = 18,444,629.5
If the quotient is a whole number, then 2 and 18,444,629.5 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 | 36,889,259 | |
| -1 | -36,889,259 |
Now, we try dividing 36,889,259 by 3:
36,889,259 ÷ 3 = 12,296,419.6667
If the quotient is a whole number, then 3 and 12,296,419.6667 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 | 36,889,259 | |
| -1 | -36,889,259 |
Let's try dividing by 4:
36,889,259 ÷ 4 = 9,222,314.75
If the quotient is a whole number, then 4 and 9,222,314.75 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 | 36,889,259 | |
| -1 | 36,889,259 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 233 | 389 | 407 | 2,563 | 4,279 | 8,621 | 14,393 | 90,637 | 94,831 | 158,323 | 997,007 | 3,353,569 | 36,889,259 |
| -1 | -11 | -37 | -233 | -389 | -407 | -2,563 | -4,279 | -8,621 | -14,393 | -90,637 | -94,831 | -158,323 | -997,007 | -3,353,569 | -36,889,259 |
