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 351,712,565, 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 | 351,712,565 | |
| -1 | -351,712,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,712,565.
Example:
1 x 351,712,565 = 351,712,565
and
-1 x -351,712,565 = 351,712,565
Notice both answers equal 351,712,565
With that explanation out of the way, let's continue. Next, we take the number 351,712,565 and divide it by 2:
351,712,565 ÷ 2 = 175,856,282.5
If the quotient is a whole number, then 2 and 175,856,282.5 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 | 351,712,565 | |
| -1 | -351,712,565 |
Now, we try dividing 351,712,565 by 3:
351,712,565 ÷ 3 = 117,237,521.6667
If the quotient is a whole number, then 3 and 117,237,521.6667 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 | 351,712,565 | |
| -1 | -351,712,565 |
Let's try dividing by 4:
351,712,565 ÷ 4 = 87,928,141.25
If the quotient is a whole number, then 4 and 87,928,141.25 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 | 351,712,565 | |
| -1 | 351,712,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 137 | 185 | 685 | 5,069 | 13,877 | 25,345 | 69,385 | 513,449 | 1,901,149 | 2,567,245 | 9,505,745 | 70,342,513 | 351,712,565 |
| -1 | -5 | -37 | -137 | -185 | -685 | -5,069 | -13,877 | -25,345 | -69,385 | -513,449 | -1,901,149 | -2,567,245 | -9,505,745 | -70,342,513 | -351,712,565 |
