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 4,200,283, 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 | 4,200,283 | |
| -1 | -4,200,283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,200,283.
Example:
1 x 4,200,283 = 4,200,283
and
-1 x -4,200,283 = 4,200,283
Notice both answers equal 4,200,283
With that explanation out of the way, let's continue. Next, we take the number 4,200,283 and divide it by 2:
4,200,283 ÷ 2 = 2,100,141.5
If the quotient is a whole number, then 2 and 2,100,141.5 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 | 4,200,283 | |
| -1 | -4,200,283 |
Now, we try dividing 4,200,283 by 3:
4,200,283 ÷ 3 = 1,400,094.3333
If the quotient is a whole number, then 3 and 1,400,094.3333 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 | 4,200,283 | |
| -1 | -4,200,283 |
Let's try dividing by 4:
4,200,283 ÷ 4 = 1,050,070.75
If the quotient is a whole number, then 4 and 1,050,070.75 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 | 4,200,283 | |
| -1 | 4,200,283 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 43 | 137 | 713 | 989 | 1,333 | 3,151 | 4,247 | 5,891 | 30,659 | 97,681 | 135,493 | 182,621 | 4,200,283 |
| -1 | -23 | -31 | -43 | -137 | -713 | -989 | -1,333 | -3,151 | -4,247 | -5,891 | -30,659 | -97,681 | -135,493 | -182,621 | -4,200,283 |
