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 42,266,659, 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 | 42,266,659 | |
| -1 | -42,266,659 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,266,659.
Example:
1 x 42,266,659 = 42,266,659
and
-1 x -42,266,659 = 42,266,659
Notice both answers equal 42,266,659
With that explanation out of the way, let's continue. Next, we take the number 42,266,659 and divide it by 2:
42,266,659 ÷ 2 = 21,133,329.5
If the quotient is a whole number, then 2 and 21,133,329.5 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 | 42,266,659 | |
| -1 | -42,266,659 |
Now, we try dividing 42,266,659 by 3:
42,266,659 ÷ 3 = 14,088,886.3333
If the quotient is a whole number, then 3 and 14,088,886.3333 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 | 42,266,659 | |
| -1 | -42,266,659 |
Let's try dividing by 4:
42,266,659 ÷ 4 = 10,566,664.75
If the quotient is a whole number, then 4 and 10,566,664.75 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 | 42,266,659 | |
| -1 | 42,266,659 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 79 | 551 | 971 | 1,501 | 2,291 | 18,449 | 28,159 | 43,529 | 76,709 | 535,021 | 1,457,471 | 2,224,561 | 42,266,659 |
| -1 | -19 | -29 | -79 | -551 | -971 | -1,501 | -2,291 | -18,449 | -28,159 | -43,529 | -76,709 | -535,021 | -1,457,471 | -2,224,561 | -42,266,659 |
