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 430,024,045, 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 | 430,024,045 | |
| -1 | -430,024,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,024,045.
Example:
1 x 430,024,045 = 430,024,045
and
-1 x -430,024,045 = 430,024,045
Notice both answers equal 430,024,045
With that explanation out of the way, let's continue. Next, we take the number 430,024,045 and divide it by 2:
430,024,045 ÷ 2 = 215,012,022.5
If the quotient is a whole number, then 2 and 215,012,022.5 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 | 430,024,045 | |
| -1 | -430,024,045 |
Now, we try dividing 430,024,045 by 3:
430,024,045 ÷ 3 = 143,341,348.3333
If the quotient is a whole number, then 3 and 143,341,348.3333 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 | 430,024,045 | |
| -1 | -430,024,045 |
Let's try dividing by 4:
430,024,045 ÷ 4 = 107,506,011.25
If the quotient is a whole number, then 4 and 107,506,011.25 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 | 430,024,045 | |
| -1 | 430,024,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,931 | 4,049 | 9,655 | 20,245 | 21,241 | 44,539 | 106,205 | 222,695 | 7,818,619 | 39,093,095 | 86,004,809 | 430,024,045 |
| -1 | -5 | -11 | -55 | -1,931 | -4,049 | -9,655 | -20,245 | -21,241 | -44,539 | -106,205 | -222,695 | -7,818,619 | -39,093,095 | -86,004,809 | -430,024,045 |
