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 42,672,305, 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 | 42,672,305 | |
| -1 | -42,672,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,672,305.
Example:
1 x 42,672,305 = 42,672,305
and
-1 x -42,672,305 = 42,672,305
Notice both answers equal 42,672,305
With that explanation out of the way, let's continue. Next, we take the number 42,672,305 and divide it by 2:
42,672,305 ÷ 2 = 21,336,152.5
If the quotient is a whole number, then 2 and 21,336,152.5 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 | 42,672,305 | |
| -1 | -42,672,305 |
Now, we try dividing 42,672,305 by 3:
42,672,305 ÷ 3 = 14,224,101.6667
If the quotient is a whole number, then 3 and 14,224,101.6667 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 | 42,672,305 | |
| -1 | -42,672,305 |
Let's try dividing by 4:
42,672,305 ÷ 4 = 10,668,076.25
If the quotient is a whole number, then 4 and 10,668,076.25 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 | 42,672,305 | |
| -1 | 42,672,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 139 | 695 | 1,807 | 4,723 | 9,035 | 23,615 | 61,399 | 306,995 | 656,497 | 3,282,485 | 8,534,461 | 42,672,305 |
| -1 | -5 | -13 | -65 | -139 | -695 | -1,807 | -4,723 | -9,035 | -23,615 | -61,399 | -306,995 | -656,497 | -3,282,485 | -8,534,461 | -42,672,305 |
