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 1,975,045, 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 | 1,975,045 | |
| -1 | -1,975,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,975,045.
Example:
1 x 1,975,045 = 1,975,045
and
-1 x -1,975,045 = 1,975,045
Notice both answers equal 1,975,045
With that explanation out of the way, let's continue. Next, we take the number 1,975,045 and divide it by 2:
1,975,045 ÷ 2 = 987,522.5
If the quotient is a whole number, then 2 and 987,522.5 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 | 1,975,045 | |
| -1 | -1,975,045 |
Now, we try dividing 1,975,045 by 3:
1,975,045 ÷ 3 = 658,348.3333
If the quotient is a whole number, then 3 and 658,348.3333 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 | 1,975,045 | |
| -1 | -1,975,045 |
Let's try dividing by 4:
1,975,045 ÷ 4 = 493,761.25
If the quotient is a whole number, then 4 and 493,761.25 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 | 1,975,045 | |
| -1 | 1,975,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 257 | 265 | 1,285 | 1,537 | 7,453 | 7,685 | 13,621 | 37,265 | 68,105 | 395,009 | 1,975,045 |
| -1 | -5 | -29 | -53 | -145 | -257 | -265 | -1,285 | -1,537 | -7,453 | -7,685 | -13,621 | -37,265 | -68,105 | -395,009 | -1,975,045 |
