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 42,134,323, 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 | 42,134,323 | |
| -1 | -42,134,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,134,323.
Example:
1 x 42,134,323 = 42,134,323
and
-1 x -42,134,323 = 42,134,323
Notice both answers equal 42,134,323
With that explanation out of the way, let's continue. Next, we take the number 42,134,323 and divide it by 2:
42,134,323 ÷ 2 = 21,067,161.5
If the quotient is a whole number, then 2 and 21,067,161.5 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 | 42,134,323 | |
| -1 | -42,134,323 |
Now, we try dividing 42,134,323 by 3:
42,134,323 ÷ 3 = 14,044,774.3333
If the quotient is a whole number, then 3 and 14,044,774.3333 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 | 42,134,323 | |
| -1 | -42,134,323 |
Let's try dividing by 4:
42,134,323 ÷ 4 = 10,533,580.75
If the quotient is a whole number, then 4 and 10,533,580.75 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 | 42,134,323 | |
| -1 | 42,134,323 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 173 | 1,211 | 1,903 | 3,163 | 13,321 | 22,141 | 34,793 | 243,551 | 547,199 | 3,830,393 | 6,019,189 | 42,134,323 |
| -1 | -7 | -11 | -77 | -173 | -1,211 | -1,903 | -3,163 | -13,321 | -22,141 | -34,793 | -243,551 | -547,199 | -3,830,393 | -6,019,189 | -42,134,323 |
