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 13,748,273, 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 | 13,748,273 | |
| -1 | -13,748,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,748,273.
Example:
1 x 13,748,273 = 13,748,273
and
-1 x -13,748,273 = 13,748,273
Notice both answers equal 13,748,273
With that explanation out of the way, let's continue. Next, we take the number 13,748,273 and divide it by 2:
13,748,273 ÷ 2 = 6,874,136.5
If the quotient is a whole number, then 2 and 6,874,136.5 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 | 13,748,273 | |
| -1 | -13,748,273 |
Now, we try dividing 13,748,273 by 3:
13,748,273 ÷ 3 = 4,582,757.6667
If the quotient is a whole number, then 3 and 4,582,757.6667 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 | 13,748,273 | |
| -1 | -13,748,273 |
Let's try dividing by 4:
13,748,273 ÷ 4 = 3,437,068.25
If the quotient is a whole number, then 4 and 3,437,068.25 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 | 13,748,273 | |
| -1 | 13,748,273 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 49 | 77 | 161 | 253 | 539 | 1,109 | 1,127 | 1,771 | 7,763 | 12,199 | 12,397 | 25,507 | 54,341 | 85,393 | 178,549 | 280,577 | 597,751 | 1,249,843 | 1,964,039 | 13,748,273 |
| -1 | -7 | -11 | -23 | -49 | -77 | -161 | -253 | -539 | -1,109 | -1,127 | -1,771 | -7,763 | -12,199 | -12,397 | -25,507 | -54,341 | -85,393 | -178,549 | -280,577 | -597,751 | -1,249,843 | -1,964,039 | -13,748,273 |
