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 42,584,425, 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 | 42,584,425 | |
| -1 | -42,584,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,584,425.
Example:
1 x 42,584,425 = 42,584,425
and
-1 x -42,584,425 = 42,584,425
Notice both answers equal 42,584,425
With that explanation out of the way, let's continue. Next, we take the number 42,584,425 and divide it by 2:
42,584,425 ÷ 2 = 21,292,212.5
If the quotient is a whole number, then 2 and 21,292,212.5 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 | 42,584,425 | |
| -1 | -42,584,425 |
Now, we try dividing 42,584,425 by 3:
42,584,425 ÷ 3 = 14,194,808.3333
If the quotient is a whole number, then 3 and 14,194,808.3333 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 | 42,584,425 | |
| -1 | -42,584,425 |
Let's try dividing by 4:
42,584,425 ÷ 4 = 10,646,106.25
If the quotient is a whole number, then 4 and 10,646,106.25 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 | 42,584,425 | |
| -1 | 42,584,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 283 | 325 | 463 | 1,415 | 2,315 | 3,679 | 6,019 | 7,075 | 11,575 | 18,395 | 30,095 | 91,975 | 131,029 | 150,475 | 655,145 | 1,703,377 | 3,275,725 | 8,516,885 | 42,584,425 |
| -1 | -5 | -13 | -25 | -65 | -283 | -325 | -463 | -1,415 | -2,315 | -3,679 | -6,019 | -7,075 | -11,575 | -18,395 | -30,095 | -91,975 | -131,029 | -150,475 | -655,145 | -1,703,377 | -3,275,725 | -8,516,885 | -42,584,425 |
