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 741,144, 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 | 741,144 | |
| -1 | -741,144 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,144.
Example:
1 x 741,144 = 741,144
and
-1 x -741,144 = 741,144
Notice both answers equal 741,144
With that explanation out of the way, let's continue. Next, we take the number 741,144 and divide it by 2:
741,144 ÷ 2 = 370,572
If the quotient is a whole number, then 2 and 370,572 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 370,572 | 741,144 | |
| -1 | -2 | -370,572 | -741,144 |
Now, we try dividing 741,144 by 3:
741,144 ÷ 3 = 247,048
If the quotient is a whole number, then 3 and 247,048 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 247,048 | 370,572 | 741,144 | |
| -1 | -2 | -3 | -247,048 | -370,572 | -741,144 |
Let's try dividing by 4:
741,144 ÷ 4 = 185,286
If the quotient is a whole number, then 4 and 185,286 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 185,286 | 247,048 | 370,572 | 741,144 | |
| -1 | -2 | -3 | -4 | -185,286 | -247,048 | -370,572 | 741,144 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 6 | 8 | 12 | 24 | 30,881 | 61,762 | 92,643 | 123,524 | 185,286 | 247,048 | 370,572 | 741,144 |
| -1 | -2 | -3 | -4 | -6 | -8 | -12 | -24 | -30,881 | -61,762 | -92,643 | -123,524 | -185,286 | -247,048 | -370,572 | -741,144 |
