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 436,140,005, 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 | 436,140,005 | |
| -1 | -436,140,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 436,140,005.
Example:
1 x 436,140,005 = 436,140,005
and
-1 x -436,140,005 = 436,140,005
Notice both answers equal 436,140,005
With that explanation out of the way, let's continue. Next, we take the number 436,140,005 and divide it by 2:
436,140,005 ÷ 2 = 218,070,002.5
If the quotient is a whole number, then 2 and 218,070,002.5 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 | 436,140,005 | |
| -1 | -436,140,005 |
Now, we try dividing 436,140,005 by 3:
436,140,005 ÷ 3 = 145,380,001.6667
If the quotient is a whole number, then 3 and 145,380,001.6667 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 | 436,140,005 | |
| -1 | -436,140,005 |
Let's try dividing by 4:
436,140,005 ÷ 4 = 109,035,001.25
If the quotient is a whole number, then 4 and 109,035,001.25 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 | 436,140,005 | |
| -1 | 436,140,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,341 | 5,323 | 11,705 | 16,387 | 26,615 | 37,261 | 81,935 | 186,305 | 12,461,143 | 62,305,715 | 87,228,001 | 436,140,005 |
| -1 | -5 | -7 | -35 | -2,341 | -5,323 | -11,705 | -16,387 | -26,615 | -37,261 | -81,935 | -186,305 | -12,461,143 | -62,305,715 | -87,228,001 | -436,140,005 |
