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 4,188,325, 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 | 4,188,325 | |
| -1 | -4,188,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,188,325.
Example:
1 x 4,188,325 = 4,188,325
and
-1 x -4,188,325 = 4,188,325
Notice both answers equal 4,188,325
With that explanation out of the way, let's continue. Next, we take the number 4,188,325 and divide it by 2:
4,188,325 ÷ 2 = 2,094,162.5
If the quotient is a whole number, then 2 and 2,094,162.5 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 | 4,188,325 | |
| -1 | -4,188,325 |
Now, we try dividing 4,188,325 by 3:
4,188,325 ÷ 3 = 1,396,108.3333
If the quotient is a whole number, then 3 and 1,396,108.3333 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 | 4,188,325 | |
| -1 | -4,188,325 |
Let's try dividing by 4:
4,188,325 ÷ 4 = 1,047,081.25
If the quotient is a whole number, then 4 and 1,047,081.25 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 | 4,188,325 | |
| -1 | 4,188,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 53 | 109 | 145 | 265 | 545 | 725 | 1,325 | 1,537 | 2,725 | 3,161 | 5,777 | 7,685 | 15,805 | 28,885 | 38,425 | 79,025 | 144,425 | 167,533 | 837,665 | 4,188,325 |
| -1 | -5 | -25 | -29 | -53 | -109 | -145 | -265 | -545 | -725 | -1,325 | -1,537 | -2,725 | -3,161 | -5,777 | -7,685 | -15,805 | -28,885 | -38,425 | -79,025 | -144,425 | -167,533 | -837,665 | -4,188,325 |
