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 400,530,353, 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 | 400,530,353 | |
| -1 | -400,530,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 400,530,353.
Example:
1 x 400,530,353 = 400,530,353
and
-1 x -400,530,353 = 400,530,353
Notice both answers equal 400,530,353
With that explanation out of the way, let's continue. Next, we take the number 400,530,353 and divide it by 2:
400,530,353 ÷ 2 = 200,265,176.5
If the quotient is a whole number, then 2 and 200,265,176.5 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 | 400,530,353 | |
| -1 | -400,530,353 |
Now, we try dividing 400,530,353 by 3:
400,530,353 ÷ 3 = 133,510,117.6667
If the quotient is a whole number, then 3 and 133,510,117.6667 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 | 400,530,353 | |
| -1 | -400,530,353 |
Let's try dividing by 4:
400,530,353 ÷ 4 = 100,132,588.25
If the quotient is a whole number, then 4 and 100,132,588.25 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 | 400,530,353 | |
| -1 | 400,530,353 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 197 | 697 | 2,917 | 3,349 | 8,077 | 49,589 | 119,597 | 137,309 | 574,649 | 2,033,149 | 9,769,033 | 23,560,609 | 400,530,353 |
| -1 | -17 | -41 | -197 | -697 | -2,917 | -3,349 | -8,077 | -49,589 | -119,597 | -137,309 | -574,649 | -2,033,149 | -9,769,033 | -23,560,609 | -400,530,353 |
