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 427,520,635, 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 | 427,520,635 | |
| -1 | -427,520,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 427,520,635.
Example:
1 x 427,520,635 = 427,520,635
and
-1 x -427,520,635 = 427,520,635
Notice both answers equal 427,520,635
With that explanation out of the way, let's continue. Next, we take the number 427,520,635 and divide it by 2:
427,520,635 ÷ 2 = 213,760,317.5
If the quotient is a whole number, then 2 and 213,760,317.5 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 | 427,520,635 | |
| -1 | -427,520,635 |
Now, we try dividing 427,520,635 by 3:
427,520,635 ÷ 3 = 142,506,878.3333
If the quotient is a whole number, then 3 and 142,506,878.3333 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 | 427,520,635 | |
| -1 | -427,520,635 |
Let's try dividing by 4:
427,520,635 ÷ 4 = 106,880,158.75
If the quotient is a whole number, then 4 and 106,880,158.75 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 | 427,520,635 | |
| -1 | 427,520,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 67 | 305 | 335 | 4,087 | 20,435 | 20,921 | 104,605 | 1,276,181 | 1,401,707 | 6,380,905 | 7,008,535 | 85,504,127 | 427,520,635 |
| -1 | -5 | -61 | -67 | -305 | -335 | -4,087 | -20,435 | -20,921 | -104,605 | -1,276,181 | -1,401,707 | -6,380,905 | -7,008,535 | -85,504,127 | -427,520,635 |
