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 513,430,603, 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 | 513,430,603 | |
| -1 | -513,430,603 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 513,430,603.
Example:
1 x 513,430,603 = 513,430,603
and
-1 x -513,430,603 = 513,430,603
Notice both answers equal 513,430,603
With that explanation out of the way, let's continue. Next, we take the number 513,430,603 and divide it by 2:
513,430,603 ÷ 2 = 256,715,301.5
If the quotient is a whole number, then 2 and 256,715,301.5 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 | 513,430,603 | |
| -1 | -513,430,603 |
Now, we try dividing 513,430,603 by 3:
513,430,603 ÷ 3 = 171,143,534.3333
If the quotient is a whole number, then 3 and 171,143,534.3333 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 | 513,430,603 | |
| -1 | -513,430,603 |
Let's try dividing by 4:
513,430,603 ÷ 4 = 128,357,650.75
If the quotient is a whole number, then 4 and 128,357,650.75 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 | 513,430,603 | |
| -1 | 513,430,603 |
If you did it right, you will end up with this table:
| 1 | 7 | 97 | 163 | 679 | 1,141 | 4,639 | 15,811 | 32,473 | 110,677 | 449,983 | 756,157 | 3,149,881 | 5,293,099 | 73,347,229 | 513,430,603 |
| -1 | -7 | -97 | -163 | -679 | -1,141 | -4,639 | -15,811 | -32,473 | -110,677 | -449,983 | -756,157 | -3,149,881 | -5,293,099 | -73,347,229 | -513,430,603 |
