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 1,862,525, 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 | 1,862,525 | |
| -1 | -1,862,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,862,525.
Example:
1 x 1,862,525 = 1,862,525
and
-1 x -1,862,525 = 1,862,525
Notice both answers equal 1,862,525
With that explanation out of the way, let's continue. Next, we take the number 1,862,525 and divide it by 2:
1,862,525 ÷ 2 = 931,262.5
If the quotient is a whole number, then 2 and 931,262.5 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 | 1,862,525 | |
| -1 | -1,862,525 |
Now, we try dividing 1,862,525 by 3:
1,862,525 ÷ 3 = 620,841.6667
If the quotient is a whole number, then 3 and 620,841.6667 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 | 1,862,525 | |
| -1 | -1,862,525 |
Let's try dividing by 4:
1,862,525 ÷ 4 = 465,631.25
If the quotient is a whole number, then 4 and 465,631.25 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 | 1,862,525 | |
| -1 | 1,862,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 367 | 725 | 1,015 | 1,835 | 2,569 | 5,075 | 9,175 | 10,643 | 12,845 | 53,215 | 64,225 | 74,501 | 266,075 | 372,505 | 1,862,525 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -367 | -725 | -1,015 | -1,835 | -2,569 | -5,075 | -9,175 | -10,643 | -12,845 | -53,215 | -64,225 | -74,501 | -266,075 | -372,505 | -1,862,525 |
