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 200,210,101, 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 | 200,210,101 | |
| -1 | -200,210,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,210,101.
Example:
1 x 200,210,101 = 200,210,101
and
-1 x -200,210,101 = 200,210,101
Notice both answers equal 200,210,101
With that explanation out of the way, let's continue. Next, we take the number 200,210,101 and divide it by 2:
200,210,101 ÷ 2 = 100,105,050.5
If the quotient is a whole number, then 2 and 100,105,050.5 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 | 200,210,101 | |
| -1 | -200,210,101 |
Now, we try dividing 200,210,101 by 3:
200,210,101 ÷ 3 = 66,736,700.3333
If the quotient is a whole number, then 3 and 66,736,700.3333 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 | 200,210,101 | |
| -1 | -200,210,101 |
Let's try dividing by 4:
200,210,101 ÷ 4 = 50,052,525.25
If the quotient is a whole number, then 4 and 50,052,525.25 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 | 200,210,101 | |
| -1 | 200,210,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 529 | 2,093 | 3,703 | 4,159 | 6,877 | 29,113 | 48,139 | 54,067 | 95,657 | 378,469 | 669,599 | 1,243,541 | 2,200,111 | 8,704,787 | 15,400,777 | 28,601,443 | 200,210,101 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -529 | -2,093 | -3,703 | -4,159 | -6,877 | -29,113 | -48,139 | -54,067 | -95,657 | -378,469 | -669,599 | -1,243,541 | -2,200,111 | -8,704,787 | -15,400,777 | -28,601,443 | -200,210,101 |
