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 1,438,075, 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 | 1,438,075 | |
| -1 | -1,438,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,438,075.
Example:
1 x 1,438,075 = 1,438,075
and
-1 x -1,438,075 = 1,438,075
Notice both answers equal 1,438,075
With that explanation out of the way, let's continue. Next, we take the number 1,438,075 and divide it by 2:
1,438,075 ÷ 2 = 719,037.5
If the quotient is a whole number, then 2 and 719,037.5 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 | 1,438,075 | |
| -1 | -1,438,075 |
Now, we try dividing 1,438,075 by 3:
1,438,075 ÷ 3 = 479,358.3333
If the quotient is a whole number, then 3 and 479,358.3333 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 | 1,438,075 | |
| -1 | -1,438,075 |
Let's try dividing by 4:
1,438,075 ÷ 4 = 359,518.75
If the quotient is a whole number, then 4 and 359,518.75 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 | 1,438,075 | |
| -1 | 1,438,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 41 | 61 | 115 | 205 | 305 | 575 | 943 | 1,025 | 1,403 | 1,525 | 2,501 | 4,715 | 7,015 | 12,505 | 23,575 | 35,075 | 57,523 | 62,525 | 287,615 | 1,438,075 |
| -1 | -5 | -23 | -25 | -41 | -61 | -115 | -205 | -305 | -575 | -943 | -1,025 | -1,403 | -1,525 | -2,501 | -4,715 | -7,015 | -12,505 | -23,575 | -35,075 | -57,523 | -62,525 | -287,615 | -1,438,075 |
