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 572,744,615, 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 | 572,744,615 | |
| -1 | -572,744,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 572,744,615.
Example:
1 x 572,744,615 = 572,744,615
and
-1 x -572,744,615 = 572,744,615
Notice both answers equal 572,744,615
With that explanation out of the way, let's continue. Next, we take the number 572,744,615 and divide it by 2:
572,744,615 ÷ 2 = 286,372,307.5
If the quotient is a whole number, then 2 and 286,372,307.5 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 | 572,744,615 | |
| -1 | -572,744,615 |
Now, we try dividing 572,744,615 by 3:
572,744,615 ÷ 3 = 190,914,871.6667
If the quotient is a whole number, then 3 and 190,914,871.6667 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 | 572,744,615 | |
| -1 | -572,744,615 |
Let's try dividing by 4:
572,744,615 ÷ 4 = 143,186,153.75
If the quotient is a whole number, then 4 and 143,186,153.75 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 | 572,744,615 | |
| -1 | 572,744,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 313 | 509 | 719 | 1,565 | 2,545 | 3,595 | 159,317 | 225,047 | 365,971 | 796,585 | 1,125,235 | 1,829,855 | 114,548,923 | 572,744,615 |
| -1 | -5 | -313 | -509 | -719 | -1,565 | -2,545 | -3,595 | -159,317 | -225,047 | -365,971 | -796,585 | -1,125,235 | -1,829,855 | -114,548,923 | -572,744,615 |
