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 422,462,401, 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 | 422,462,401 | |
| -1 | -422,462,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 422,462,401.
Example:
1 x 422,462,401 = 422,462,401
and
-1 x -422,462,401 = 422,462,401
Notice both answers equal 422,462,401
With that explanation out of the way, let's continue. Next, we take the number 422,462,401 and divide it by 2:
422,462,401 ÷ 2 = 211,231,200.5
If the quotient is a whole number, then 2 and 211,231,200.5 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 | 422,462,401 | |
| -1 | -422,462,401 |
Now, we try dividing 422,462,401 by 3:
422,462,401 ÷ 3 = 140,820,800.3333
If the quotient is a whole number, then 3 and 140,820,800.3333 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 | 422,462,401 | |
| -1 | -422,462,401 |
Let's try dividing by 4:
422,462,401 ÷ 4 = 105,615,600.25
If the quotient is a whole number, then 4 and 105,615,600.25 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 | 422,462,401 | |
| -1 | 422,462,401 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 43 | 1,189 | 1,247 | 1,763 | 8,263 | 51,127 | 239,627 | 338,783 | 355,309 | 9,824,707 | 10,303,961 | 14,567,669 | 422,462,401 |
| -1 | -29 | -41 | -43 | -1,189 | -1,247 | -1,763 | -8,263 | -51,127 | -239,627 | -338,783 | -355,309 | -9,824,707 | -10,303,961 | -14,567,669 | -422,462,401 |
