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 37,800,253, 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 | 37,800,253 | |
| -1 | -37,800,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,800,253.
Example:
1 x 37,800,253 = 37,800,253
and
-1 x -37,800,253 = 37,800,253
Notice both answers equal 37,800,253
With that explanation out of the way, let's continue. Next, we take the number 37,800,253 and divide it by 2:
37,800,253 ÷ 2 = 18,900,126.5
If the quotient is a whole number, then 2 and 18,900,126.5 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 | 37,800,253 | |
| -1 | -37,800,253 |
Now, we try dividing 37,800,253 by 3:
37,800,253 ÷ 3 = 12,600,084.3333
If the quotient is a whole number, then 3 and 12,600,084.3333 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 | 37,800,253 | |
| -1 | -37,800,253 |
Let's try dividing by 4:
37,800,253 ÷ 4 = 9,450,063.25
If the quotient is a whole number, then 4 and 9,450,063.25 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 | 37,800,253 | |
| -1 | 37,800,253 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 31 | 551 | 589 | 899 | 2,213 | 17,081 | 42,047 | 64,177 | 68,603 | 1,219,363 | 1,303,457 | 1,989,487 | 37,800,253 |
| -1 | -19 | -29 | -31 | -551 | -589 | -899 | -2,213 | -17,081 | -42,047 | -64,177 | -68,603 | -1,219,363 | -1,303,457 | -1,989,487 | -37,800,253 |
