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 20,060,257, 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 | 20,060,257 | |
| -1 | -20,060,257 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,060,257.
Example:
1 x 20,060,257 = 20,060,257
and
-1 x -20,060,257 = 20,060,257
Notice both answers equal 20,060,257
With that explanation out of the way, let's continue. Next, we take the number 20,060,257 and divide it by 2:
20,060,257 ÷ 2 = 10,030,128.5
If the quotient is a whole number, then 2 and 10,030,128.5 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 | 20,060,257 | |
| -1 | -20,060,257 |
Now, we try dividing 20,060,257 by 3:
20,060,257 ÷ 3 = 6,686,752.3333
If the quotient is a whole number, then 3 and 6,686,752.3333 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 | 20,060,257 | |
| -1 | -20,060,257 |
Let's try dividing by 4:
20,060,257 ÷ 4 = 5,015,064.25
If the quotient is a whole number, then 4 and 5,015,064.25 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 | 20,060,257 | |
| -1 | 20,060,257 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 29 | 49 | 133 | 203 | 551 | 743 | 931 | 1,421 | 3,857 | 5,201 | 14,117 | 21,547 | 26,999 | 36,407 | 98,819 | 150,829 | 409,393 | 691,733 | 1,055,803 | 2,865,751 | 20,060,257 |
| -1 | -7 | -19 | -29 | -49 | -133 | -203 | -551 | -743 | -931 | -1,421 | -3,857 | -5,201 | -14,117 | -21,547 | -26,999 | -36,407 | -98,819 | -150,829 | -409,393 | -691,733 | -1,055,803 | -2,865,751 | -20,060,257 |
