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 1,653,743, 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 | 1,653,743 | |
| -1 | -1,653,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,653,743.
Example:
1 x 1,653,743 = 1,653,743
and
-1 x -1,653,743 = 1,653,743
Notice both answers equal 1,653,743
With that explanation out of the way, let's continue. Next, we take the number 1,653,743 and divide it by 2:
1,653,743 ÷ 2 = 826,871.5
If the quotient is a whole number, then 2 and 826,871.5 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 | 1,653,743 | |
| -1 | -1,653,743 |
Now, we try dividing 1,653,743 by 3:
1,653,743 ÷ 3 = 551,247.6667
If the quotient is a whole number, then 3 and 551,247.6667 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 | 1,653,743 | |
| -1 | -1,653,743 |
Let's try dividing by 4:
1,653,743 ÷ 4 = 413,435.75
If the quotient is a whole number, then 4 and 413,435.75 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 | 1,653,743 | |
| -1 | 1,653,743 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,069 | 1,547 | 7,483 | 13,897 | 18,173 | 97,279 | 127,211 | 236,249 | 1,653,743 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,069 | -1,547 | -7,483 | -13,897 | -18,173 | -97,279 | -127,211 | -236,249 | -1,653,743 |
