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 4,782,773, 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 | 4,782,773 | |
| -1 | -4,782,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,782,773.
Example:
1 x 4,782,773 = 4,782,773
and
-1 x -4,782,773 = 4,782,773
Notice both answers equal 4,782,773
With that explanation out of the way, let's continue. Next, we take the number 4,782,773 and divide it by 2:
4,782,773 ÷ 2 = 2,391,386.5
If the quotient is a whole number, then 2 and 2,391,386.5 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 | 4,782,773 | |
| -1 | -4,782,773 |
Now, we try dividing 4,782,773 by 3:
4,782,773 ÷ 3 = 1,594,257.6667
If the quotient is a whole number, then 3 and 1,594,257.6667 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 | 4,782,773 | |
| -1 | -4,782,773 |
Let's try dividing by 4:
4,782,773 ÷ 4 = 1,195,693.25
If the quotient is a whole number, then 4 and 1,195,693.25 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 | 4,782,773 | |
| -1 | 4,782,773 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 53 | 71 | 1,271 | 1,643 | 2,173 | 2,201 | 2,911 | 3,763 | 67,363 | 90,241 | 116,653 | 154,283 | 4,782,773 |
| -1 | -31 | -41 | -53 | -71 | -1,271 | -1,643 | -2,173 | -2,201 | -2,911 | -3,763 | -67,363 | -90,241 | -116,653 | -154,283 | -4,782,773 |
