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 1,973,335, 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 | 1,973,335 | |
| -1 | -1,973,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,973,335.
Example:
1 x 1,973,335 = 1,973,335
and
-1 x -1,973,335 = 1,973,335
Notice both answers equal 1,973,335
With that explanation out of the way, let's continue. Next, we take the number 1,973,335 and divide it by 2:
1,973,335 ÷ 2 = 986,667.5
If the quotient is a whole number, then 2 and 986,667.5 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 | 1,973,335 | |
| -1 | -1,973,335 |
Now, we try dividing 1,973,335 by 3:
1,973,335 ÷ 3 = 657,778.3333
If the quotient is a whole number, then 3 and 657,778.3333 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 | 1,973,335 | |
| -1 | -1,973,335 |
Let's try dividing by 4:
1,973,335 ÷ 4 = 493,333.75
If the quotient is a whole number, then 4 and 493,333.75 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 | 1,973,335 | |
| -1 | 1,973,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 4,337 | 21,685 | 30,359 | 56,381 | 151,795 | 281,905 | 394,667 | 1,973,335 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -4,337 | -21,685 | -30,359 | -56,381 | -151,795 | -281,905 | -394,667 | -1,973,335 |
