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 1,654,289, 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 | 1,654,289 | |
| -1 | -1,654,289 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,654,289.
Example:
1 x 1,654,289 = 1,654,289
and
-1 x -1,654,289 = 1,654,289
Notice both answers equal 1,654,289
With that explanation out of the way, let's continue. Next, we take the number 1,654,289 and divide it by 2:
1,654,289 ÷ 2 = 827,144.5
If the quotient is a whole number, then 2 and 827,144.5 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 | 1,654,289 | |
| -1 | -1,654,289 |
Now, we try dividing 1,654,289 by 3:
1,654,289 ÷ 3 = 551,429.6667
If the quotient is a whole number, then 3 and 551,429.6667 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 | 1,654,289 | |
| -1 | -1,654,289 |
Let's try dividing by 4:
1,654,289 ÷ 4 = 413,572.25
If the quotient is a whole number, then 4 and 413,572.25 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 | 1,654,289 | |
| -1 | 1,654,289 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 53 | 91 | 343 | 371 | 637 | 689 | 2,401 | 2,597 | 4,459 | 4,823 | 18,179 | 31,213 | 33,761 | 127,253 | 236,327 | 1,654,289 |
| -1 | -7 | -13 | -49 | -53 | -91 | -343 | -371 | -637 | -689 | -2,401 | -2,597 | -4,459 | -4,823 | -18,179 | -31,213 | -33,761 | -127,253 | -236,327 | -1,654,289 |
