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 314,421,425, 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 | 314,421,425 | |
| -1 | -314,421,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 314,421,425.
Example:
1 x 314,421,425 = 314,421,425
and
-1 x -314,421,425 = 314,421,425
Notice both answers equal 314,421,425
With that explanation out of the way, let's continue. Next, we take the number 314,421,425 and divide it by 2:
314,421,425 ÷ 2 = 157,210,712.5
If the quotient is a whole number, then 2 and 157,210,712.5 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 | 314,421,425 | |
| -1 | -314,421,425 |
Now, we try dividing 314,421,425 by 3:
314,421,425 ÷ 3 = 104,807,141.6667
If the quotient is a whole number, then 3 and 104,807,141.6667 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 | 314,421,425 | |
| -1 | -314,421,425 |
Let's try dividing by 4:
314,421,425 ÷ 4 = 78,605,356.25
If the quotient is a whole number, then 4 and 78,605,356.25 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 | 314,421,425 | |
| -1 | 314,421,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 89 | 251 | 445 | 563 | 1,255 | 2,225 | 2,815 | 6,275 | 14,075 | 22,339 | 50,107 | 111,695 | 141,313 | 250,535 | 558,475 | 706,565 | 1,252,675 | 3,532,825 | 12,576,857 | 62,884,285 | 314,421,425 |
| -1 | -5 | -25 | -89 | -251 | -445 | -563 | -1,255 | -2,225 | -2,815 | -6,275 | -14,075 | -22,339 | -50,107 | -111,695 | -141,313 | -250,535 | -558,475 | -706,565 | -1,252,675 | -3,532,825 | -12,576,857 | -62,884,285 | -314,421,425 |
