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 42,037,559, 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 | 42,037,559 | |
| -1 | -42,037,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,037,559.
Example:
1 x 42,037,559 = 42,037,559
and
-1 x -42,037,559 = 42,037,559
Notice both answers equal 42,037,559
With that explanation out of the way, let's continue. Next, we take the number 42,037,559 and divide it by 2:
42,037,559 ÷ 2 = 21,018,779.5
If the quotient is a whole number, then 2 and 21,018,779.5 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 | 42,037,559 | |
| -1 | -42,037,559 |
Now, we try dividing 42,037,559 by 3:
42,037,559 ÷ 3 = 14,012,519.6667
If the quotient is a whole number, then 3 and 14,012,519.6667 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 | 42,037,559 | |
| -1 | -42,037,559 |
Let's try dividing by 4:
42,037,559 ÷ 4 = 10,509,389.75
If the quotient is a whole number, then 4 and 10,509,389.75 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 | 42,037,559 | |
| -1 | 42,037,559 |
If you did it right, you will end up with this table:
| 1 | 29 | 59 | 79 | 311 | 1,711 | 2,291 | 4,661 | 9,019 | 18,349 | 24,569 | 135,169 | 532,121 | 712,501 | 1,449,571 | 42,037,559 |
| -1 | -29 | -59 | -79 | -311 | -1,711 | -2,291 | -4,661 | -9,019 | -18,349 | -24,569 | -135,169 | -532,121 | -712,501 | -1,449,571 | -42,037,559 |
