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 440,365,435, 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 | 440,365,435 | |
| -1 | -440,365,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,365,435.
Example:
1 x 440,365,435 = 440,365,435
and
-1 x -440,365,435 = 440,365,435
Notice both answers equal 440,365,435
With that explanation out of the way, let's continue. Next, we take the number 440,365,435 and divide it by 2:
440,365,435 ÷ 2 = 220,182,717.5
If the quotient is a whole number, then 2 and 220,182,717.5 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 | 440,365,435 | |
| -1 | -440,365,435 |
Now, we try dividing 440,365,435 by 3:
440,365,435 ÷ 3 = 146,788,478.3333
If the quotient is a whole number, then 3 and 146,788,478.3333 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 | 440,365,435 | |
| -1 | -440,365,435 |
Let's try dividing by 4:
440,365,435 ÷ 4 = 110,091,358.75
If the quotient is a whole number, then 4 and 110,091,358.75 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 | 440,365,435 | |
| -1 | 440,365,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 631 | 3,155 | 4,813 | 18,299 | 24,065 | 91,495 | 139,577 | 697,885 | 3,037,003 | 15,185,015 | 88,073,087 | 440,365,435 |
| -1 | -5 | -29 | -145 | -631 | -3,155 | -4,813 | -18,299 | -24,065 | -91,495 | -139,577 | -697,885 | -3,037,003 | -15,185,015 | -88,073,087 | -440,365,435 |
