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 42,204,425, 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 | 42,204,425 | |
| -1 | -42,204,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,204,425.
Example:
1 x 42,204,425 = 42,204,425
and
-1 x -42,204,425 = 42,204,425
Notice both answers equal 42,204,425
With that explanation out of the way, let's continue. Next, we take the number 42,204,425 and divide it by 2:
42,204,425 ÷ 2 = 21,102,212.5
If the quotient is a whole number, then 2 and 21,102,212.5 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 | 42,204,425 | |
| -1 | -42,204,425 |
Now, we try dividing 42,204,425 by 3:
42,204,425 ÷ 3 = 14,068,141.6667
If the quotient is a whole number, then 3 and 14,068,141.6667 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 | 42,204,425 | |
| -1 | -42,204,425 |
Let's try dividing by 4:
42,204,425 ÷ 4 = 10,551,106.25
If the quotient is a whole number, then 4 and 10,551,106.25 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 | 42,204,425 | |
| -1 | 42,204,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 29 | 115 | 145 | 575 | 667 | 725 | 2,531 | 3,335 | 12,655 | 16,675 | 58,213 | 63,275 | 73,399 | 291,065 | 366,995 | 1,455,325 | 1,688,177 | 1,834,975 | 8,440,885 | 42,204,425 |
| -1 | -5 | -23 | -25 | -29 | -115 | -145 | -575 | -667 | -725 | -2,531 | -3,335 | -12,655 | -16,675 | -58,213 | -63,275 | -73,399 | -291,065 | -366,995 | -1,455,325 | -1,688,177 | -1,834,975 | -8,440,885 | -42,204,425 |
