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 530,146,001, 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 | 530,146,001 | |
| -1 | -530,146,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 530,146,001.
Example:
1 x 530,146,001 = 530,146,001
and
-1 x -530,146,001 = 530,146,001
Notice both answers equal 530,146,001
With that explanation out of the way, let's continue. Next, we take the number 530,146,001 and divide it by 2:
530,146,001 ÷ 2 = 265,073,000.5
If the quotient is a whole number, then 2 and 265,073,000.5 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 | 530,146,001 | |
| -1 | -530,146,001 |
Now, we try dividing 530,146,001 by 3:
530,146,001 ÷ 3 = 176,715,333.6667
If the quotient is a whole number, then 3 and 176,715,333.6667 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 | 530,146,001 | |
| -1 | -530,146,001 |
Let's try dividing by 4:
530,146,001 ÷ 4 = 132,536,500.25
If the quotient is a whole number, then 4 and 132,536,500.25 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 | 530,146,001 | |
| -1 | 530,146,001 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 2,087 | 3,299 | 14,609 | 22,957 | 23,093 | 36,289 | 160,699 | 254,023 | 6,885,013 | 48,195,091 | 75,735,143 | 530,146,001 |
| -1 | -7 | -11 | -77 | -2,087 | -3,299 | -14,609 | -22,957 | -23,093 | -36,289 | -160,699 | -254,023 | -6,885,013 | -48,195,091 | -75,735,143 | -530,146,001 |
