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 530,042,201, 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 | 530,042,201 | |
| -1 | -530,042,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 530,042,201.
Example:
1 x 530,042,201 = 530,042,201
and
-1 x -530,042,201 = 530,042,201
Notice both answers equal 530,042,201
With that explanation out of the way, let's continue. Next, we take the number 530,042,201 and divide it by 2:
530,042,201 ÷ 2 = 265,021,100.5
If the quotient is a whole number, then 2 and 265,021,100.5 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 | 530,042,201 | |
| -1 | -530,042,201 |
Now, we try dividing 530,042,201 by 3:
530,042,201 ÷ 3 = 176,680,733.6667
If the quotient is a whole number, then 3 and 176,680,733.6667 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 | 530,042,201 | |
| -1 | -530,042,201 |
Let's try dividing by 4:
530,042,201 ÷ 4 = 132,510,550.25
If the quotient is a whole number, then 4 and 132,510,550.25 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 | 530,042,201 | |
| -1 | 530,042,201 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 401 | 5,213 | 5,981 | 6,817 | 77,753 | 88,621 | 101,677 | 1,321,801 | 2,398,381 | 31,178,953 | 40,772,477 | 530,042,201 |
| -1 | -13 | -17 | -221 | -401 | -5,213 | -5,981 | -6,817 | -77,753 | -88,621 | -101,677 | -1,321,801 | -2,398,381 | -31,178,953 | -40,772,477 | -530,042,201 |
