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 424,045,435, 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 | 424,045,435 | |
| -1 | -424,045,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 424,045,435.
Example:
1 x 424,045,435 = 424,045,435
and
-1 x -424,045,435 = 424,045,435
Notice both answers equal 424,045,435
With that explanation out of the way, let's continue. Next, we take the number 424,045,435 and divide it by 2:
424,045,435 ÷ 2 = 212,022,717.5
If the quotient is a whole number, then 2 and 212,022,717.5 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 | 424,045,435 | |
| -1 | -424,045,435 |
Now, we try dividing 424,045,435 by 3:
424,045,435 ÷ 3 = 141,348,478.3333
If the quotient is a whole number, then 3 and 141,348,478.3333 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 | 424,045,435 | |
| -1 | -424,045,435 |
Let's try dividing by 4:
424,045,435 ÷ 4 = 106,011,358.75
If the quotient is a whole number, then 4 and 106,011,358.75 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 | 424,045,435 | |
| -1 | 424,045,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 248,707 | 1,243,535 | 2,735,777 | 7,709,917 | 13,678,885 | 38,549,585 | 84,809,087 | 424,045,435 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -248,707 | -1,243,535 | -2,735,777 | -7,709,917 | -13,678,885 | -38,549,585 | -84,809,087 | -424,045,435 |
