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 42,641,755, 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 | 42,641,755 | |
| -1 | -42,641,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,641,755.
Example:
1 x 42,641,755 = 42,641,755
and
-1 x -42,641,755 = 42,641,755
Notice both answers equal 42,641,755
With that explanation out of the way, let's continue. Next, we take the number 42,641,755 and divide it by 2:
42,641,755 ÷ 2 = 21,320,877.5
If the quotient is a whole number, then 2 and 21,320,877.5 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 | 42,641,755 | |
| -1 | -42,641,755 |
Now, we try dividing 42,641,755 by 3:
42,641,755 ÷ 3 = 14,213,918.3333
If the quotient is a whole number, then 3 and 14,213,918.3333 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 | 42,641,755 | |
| -1 | -42,641,755 |
Let's try dividing by 4:
42,641,755 ÷ 4 = 10,660,438.75
If the quotient is a whole number, then 4 and 10,660,438.75 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 | 42,641,755 | |
| -1 | 42,641,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 293 | 1,465 | 2,239 | 3,809 | 11,195 | 19,045 | 29,107 | 145,535 | 656,027 | 3,280,135 | 8,528,351 | 42,641,755 |
| -1 | -5 | -13 | -65 | -293 | -1,465 | -2,239 | -3,809 | -11,195 | -19,045 | -29,107 | -145,535 | -656,027 | -3,280,135 | -8,528,351 | -42,641,755 |
