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 1,692,197, 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 | 1,692,197 | |
| -1 | -1,692,197 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,692,197.
Example:
1 x 1,692,197 = 1,692,197
and
-1 x -1,692,197 = 1,692,197
Notice both answers equal 1,692,197
With that explanation out of the way, let's continue. Next, we take the number 1,692,197 and divide it by 2:
1,692,197 ÷ 2 = 846,098.5
If the quotient is a whole number, then 2 and 846,098.5 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 | 1,692,197 | |
| -1 | -1,692,197 |
Now, we try dividing 1,692,197 by 3:
1,692,197 ÷ 3 = 564,065.6667
If the quotient is a whole number, then 3 and 564,065.6667 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 | 1,692,197 | |
| -1 | -1,692,197 |
Let's try dividing by 4:
1,692,197 ÷ 4 = 423,049.25
If the quotient is a whole number, then 4 and 423,049.25 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 | 1,692,197 | |
| -1 | 1,692,197 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 19 | 31 | 169 | 221 | 247 | 323 | 403 | 527 | 589 | 2,873 | 3,211 | 4,199 | 5,239 | 6,851 | 7,657 | 10,013 | 54,587 | 89,063 | 99,541 | 130,169 | 1,692,197 |
| -1 | -13 | -17 | -19 | -31 | -169 | -221 | -247 | -323 | -403 | -527 | -589 | -2,873 | -3,211 | -4,199 | -5,239 | -6,851 | -7,657 | -10,013 | -54,587 | -89,063 | -99,541 | -130,169 | -1,692,197 |
