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 42,300,037, 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 | 42,300,037 | |
| -1 | -42,300,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,300,037.
Example:
1 x 42,300,037 = 42,300,037
and
-1 x -42,300,037 = 42,300,037
Notice both answers equal 42,300,037
With that explanation out of the way, let's continue. Next, we take the number 42,300,037 and divide it by 2:
42,300,037 ÷ 2 = 21,150,018.5
If the quotient is a whole number, then 2 and 21,150,018.5 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 | 42,300,037 | |
| -1 | -42,300,037 |
Now, we try dividing 42,300,037 by 3:
42,300,037 ÷ 3 = 14,100,012.3333
If the quotient is a whole number, then 3 and 14,100,012.3333 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 | 42,300,037 | |
| -1 | -42,300,037 |
Let's try dividing by 4:
42,300,037 ÷ 4 = 10,575,009.25
If the quotient is a whole number, then 4 and 10,575,009.25 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 | 42,300,037 | |
| -1 | 42,300,037 |
If you did it right, you will end up with this table:
| 1 | 13 | 83 | 197 | 199 | 1,079 | 2,561 | 2,587 | 16,351 | 16,517 | 39,203 | 212,563 | 214,721 | 509,639 | 3,253,849 | 42,300,037 |
| -1 | -13 | -83 | -197 | -199 | -1,079 | -2,561 | -2,587 | -16,351 | -16,517 | -39,203 | -212,563 | -214,721 | -509,639 | -3,253,849 | -42,300,037 |
