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 619,225, 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 | 619,225 | |
| -1 | -619,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 619,225.
Example:
1 x 619,225 = 619,225
and
-1 x -619,225 = 619,225
Notice both answers equal 619,225
With that explanation out of the way, let's continue. Next, we take the number 619,225 and divide it by 2:
619,225 ÷ 2 = 309,612.5
If the quotient is a whole number, then 2 and 309,612.5 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 | 619,225 | |
| -1 | -619,225 |
Now, we try dividing 619,225 by 3:
619,225 ÷ 3 = 206,408.3333
If the quotient is a whole number, then 3 and 206,408.3333 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 | 619,225 | |
| -1 | -619,225 |
Let's try dividing by 4:
619,225 ÷ 4 = 154,806.25
If the quotient is a whole number, then 4 and 154,806.25 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 | 619,225 | |
| -1 | 619,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 31 | 47 | 85 | 155 | 235 | 425 | 527 | 775 | 799 | 1,175 | 1,457 | 2,635 | 3,995 | 7,285 | 13,175 | 19,975 | 24,769 | 36,425 | 123,845 | 619,225 |
| -1 | -5 | -17 | -25 | -31 | -47 | -85 | -155 | -235 | -425 | -527 | -775 | -799 | -1,175 | -1,457 | -2,635 | -3,995 | -7,285 | -13,175 | -19,975 | -24,769 | -36,425 | -123,845 | -619,225 |
