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 4,237,375, 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 | 4,237,375 | |
| -1 | -4,237,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,237,375.
Example:
1 x 4,237,375 = 4,237,375
and
-1 x -4,237,375 = 4,237,375
Notice both answers equal 4,237,375
With that explanation out of the way, let's continue. Next, we take the number 4,237,375 and divide it by 2:
4,237,375 ÷ 2 = 2,118,687.5
If the quotient is a whole number, then 2 and 2,118,687.5 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 | 4,237,375 | |
| -1 | -4,237,375 |
Now, we try dividing 4,237,375 by 3:
4,237,375 ÷ 3 = 1,412,458.3333
If the quotient is a whole number, then 3 and 1,412,458.3333 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 | 4,237,375 | |
| -1 | -4,237,375 |
Let's try dividing by 4:
4,237,375 ÷ 4 = 1,059,343.75
If the quotient is a whole number, then 4 and 1,059,343.75 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 | 4,237,375 | |
| -1 | 4,237,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 109 | 125 | 311 | 545 | 1,555 | 2,725 | 7,775 | 13,625 | 33,899 | 38,875 | 169,495 | 847,475 | 4,237,375 |
| -1 | -5 | -25 | -109 | -125 | -311 | -545 | -1,555 | -2,725 | -7,775 | -13,625 | -33,899 | -38,875 | -169,495 | -847,475 | -4,237,375 |
