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 203,643,037, 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 | 203,643,037 | |
| -1 | -203,643,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,643,037.
Example:
1 x 203,643,037 = 203,643,037
and
-1 x -203,643,037 = 203,643,037
Notice both answers equal 203,643,037
With that explanation out of the way, let's continue. Next, we take the number 203,643,037 and divide it by 2:
203,643,037 ÷ 2 = 101,821,518.5
If the quotient is a whole number, then 2 and 101,821,518.5 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 | 203,643,037 | |
| -1 | -203,643,037 |
Now, we try dividing 203,643,037 by 3:
203,643,037 ÷ 3 = 67,881,012.3333
If the quotient is a whole number, then 3 and 67,881,012.3333 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 | 203,643,037 | |
| -1 | -203,643,037 |
Let's try dividing by 4:
203,643,037 ÷ 4 = 50,910,759.25
If the quotient is a whole number, then 4 and 50,910,759.25 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 | 203,643,037 | |
| -1 | 203,643,037 |
If you did it right, you will end up with this table:
| 1 | 13 | 131 | 197 | 607 | 1,703 | 2,561 | 7,891 | 25,807 | 79,517 | 119,579 | 335,491 | 1,033,721 | 1,554,527 | 15,664,849 | 203,643,037 |
| -1 | -13 | -131 | -197 | -607 | -1,703 | -2,561 | -7,891 | -25,807 | -79,517 | -119,579 | -335,491 | -1,033,721 | -1,554,527 | -15,664,849 | -203,643,037 |
