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 477,152,431, 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 | 477,152,431 | |
| -1 | -477,152,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 477,152,431.
Example:
1 x 477,152,431 = 477,152,431
and
-1 x -477,152,431 = 477,152,431
Notice both answers equal 477,152,431
With that explanation out of the way, let's continue. Next, we take the number 477,152,431 and divide it by 2:
477,152,431 ÷ 2 = 238,576,215.5
If the quotient is a whole number, then 2 and 238,576,215.5 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 | 477,152,431 | |
| -1 | -477,152,431 |
Now, we try dividing 477,152,431 by 3:
477,152,431 ÷ 3 = 159,050,810.3333
If the quotient is a whole number, then 3 and 159,050,810.3333 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 | 477,152,431 | |
| -1 | -477,152,431 |
Let's try dividing by 4:
477,152,431 ÷ 4 = 119,288,107.75
If the quotient is a whole number, then 4 and 119,288,107.75 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 | 477,152,431 | |
| -1 | 477,152,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 223 | 427 | 1,561 | 5,011 | 13,603 | 35,077 | 95,221 | 305,671 | 1,117,453 | 2,139,697 | 7,822,171 | 68,164,633 | 477,152,431 |
| -1 | -7 | -61 | -223 | -427 | -1,561 | -5,011 | -13,603 | -35,077 | -95,221 | -305,671 | -1,117,453 | -2,139,697 | -7,822,171 | -68,164,633 | -477,152,431 |
