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 430,527,137, 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 | 430,527,137 | |
| -1 | -430,527,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,527,137.
Example:
1 x 430,527,137 = 430,527,137
and
-1 x -430,527,137 = 430,527,137
Notice both answers equal 430,527,137
With that explanation out of the way, let's continue. Next, we take the number 430,527,137 and divide it by 2:
430,527,137 ÷ 2 = 215,263,568.5
If the quotient is a whole number, then 2 and 215,263,568.5 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 | 430,527,137 | |
| -1 | -430,527,137 |
Now, we try dividing 430,527,137 by 3:
430,527,137 ÷ 3 = 143,509,045.6667
If the quotient is a whole number, then 3 and 143,509,045.6667 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 | 430,527,137 | |
| -1 | -430,527,137 |
Let's try dividing by 4:
430,527,137 ÷ 4 = 107,631,784.25
If the quotient is a whole number, then 4 and 107,631,784.25 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 | 430,527,137 | |
| -1 | 430,527,137 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 433 | 817 | 1,217 | 8,227 | 18,619 | 23,123 | 52,331 | 353,761 | 526,961 | 994,289 | 10,012,259 | 22,659,323 | 430,527,137 |
| -1 | -19 | -43 | -433 | -817 | -1,217 | -8,227 | -18,619 | -23,123 | -52,331 | -353,761 | -526,961 | -994,289 | -10,012,259 | -22,659,323 | -430,527,137 |
