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 1,702,225, 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 | 1,702,225 | |
| -1 | -1,702,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,702,225.
Example:
1 x 1,702,225 = 1,702,225
and
-1 x -1,702,225 = 1,702,225
Notice both answers equal 1,702,225
With that explanation out of the way, let's continue. Next, we take the number 1,702,225 and divide it by 2:
1,702,225 ÷ 2 = 851,112.5
If the quotient is a whole number, then 2 and 851,112.5 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 | 1,702,225 | |
| -1 | -1,702,225 |
Now, we try dividing 1,702,225 by 3:
1,702,225 ÷ 3 = 567,408.3333
If the quotient is a whole number, then 3 and 567,408.3333 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 | 1,702,225 | |
| -1 | -1,702,225 |
Let's try dividing by 4:
1,702,225 ÷ 4 = 425,556.25
If the quotient is a whole number, then 4 and 425,556.25 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 | 1,702,225 | |
| -1 | 1,702,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 71 | 137 | 175 | 355 | 497 | 685 | 959 | 1,775 | 2,485 | 3,425 | 4,795 | 9,727 | 12,425 | 23,975 | 48,635 | 68,089 | 243,175 | 340,445 | 1,702,225 |
| -1 | -5 | -7 | -25 | -35 | -71 | -137 | -175 | -355 | -497 | -685 | -959 | -1,775 | -2,485 | -3,425 | -4,795 | -9,727 | -12,425 | -23,975 | -48,635 | -68,089 | -243,175 | -340,445 | -1,702,225 |
