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 210,524,041, 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 | 210,524,041 | |
| -1 | -210,524,041 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 210,524,041.
Example:
1 x 210,524,041 = 210,524,041
and
-1 x -210,524,041 = 210,524,041
Notice both answers equal 210,524,041
With that explanation out of the way, let's continue. Next, we take the number 210,524,041 and divide it by 2:
210,524,041 ÷ 2 = 105,262,020.5
If the quotient is a whole number, then 2 and 105,262,020.5 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 | 210,524,041 | |
| -1 | -210,524,041 |
Now, we try dividing 210,524,041 by 3:
210,524,041 ÷ 3 = 70,174,680.3333
If the quotient is a whole number, then 3 and 70,174,680.3333 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 | 210,524,041 | |
| -1 | -210,524,041 |
Let's try dividing by 4:
210,524,041 ÷ 4 = 52,631,010.25
If the quotient is a whole number, then 4 and 52,631,010.25 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 | 210,524,041 | |
| -1 | 210,524,041 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 167 | 637 | 1,169 | 1,979 | 2,171 | 8,183 | 13,853 | 15,197 | 25,727 | 96,971 | 106,379 | 180,089 | 330,493 | 1,260,623 | 2,313,451 | 4,296,409 | 16,194,157 | 30,074,863 | 210,524,041 |
| -1 | -7 | -13 | -49 | -91 | -167 | -637 | -1,169 | -1,979 | -2,171 | -8,183 | -13,853 | -15,197 | -25,727 | -96,971 | -106,379 | -180,089 | -330,493 | -1,260,623 | -2,313,451 | -4,296,409 | -16,194,157 | -30,074,863 | -210,524,041 |
