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 102,000,425, 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 | 102,000,425 | |
| -1 | -102,000,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,000,425.
Example:
1 x 102,000,425 = 102,000,425
and
-1 x -102,000,425 = 102,000,425
Notice both answers equal 102,000,425
With that explanation out of the way, let's continue. Next, we take the number 102,000,425 and divide it by 2:
102,000,425 ÷ 2 = 51,000,212.5
If the quotient is a whole number, then 2 and 51,000,212.5 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 | 102,000,425 | |
| -1 | -102,000,425 |
Now, we try dividing 102,000,425 by 3:
102,000,425 ÷ 3 = 34,000,141.6667
If the quotient is a whole number, then 3 and 34,000,141.6667 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 | 102,000,425 | |
| -1 | -102,000,425 |
Let's try dividing by 4:
102,000,425 ÷ 4 = 25,500,106.25
If the quotient is a whole number, then 4 and 25,500,106.25 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 | 102,000,425 | |
| -1 | 102,000,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 107 | 425 | 535 | 1,819 | 2,243 | 2,675 | 9,095 | 11,215 | 38,131 | 45,475 | 56,075 | 190,655 | 240,001 | 953,275 | 1,200,005 | 4,080,017 | 6,000,025 | 20,400,085 | 102,000,425 |
| -1 | -5 | -17 | -25 | -85 | -107 | -425 | -535 | -1,819 | -2,243 | -2,675 | -9,095 | -11,215 | -38,131 | -45,475 | -56,075 | -190,655 | -240,001 | -953,275 | -1,200,005 | -4,080,017 | -6,000,025 | -20,400,085 | -102,000,425 |
