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 156,365,293, 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 | 156,365,293 | |
| -1 | -156,365,293 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,365,293.
Example:
1 x 156,365,293 = 156,365,293
and
-1 x -156,365,293 = 156,365,293
Notice both answers equal 156,365,293
With that explanation out of the way, let's continue. Next, we take the number 156,365,293 and divide it by 2:
156,365,293 ÷ 2 = 78,182,646.5
If the quotient is a whole number, then 2 and 78,182,646.5 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 | 156,365,293 | |
| -1 | -156,365,293 |
Now, we try dividing 156,365,293 by 3:
156,365,293 ÷ 3 = 52,121,764.3333
If the quotient is a whole number, then 3 and 52,121,764.3333 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 | 156,365,293 | |
| -1 | -156,365,293 |
Let's try dividing by 4:
156,365,293 ÷ 4 = 39,091,323.25
If the quotient is a whole number, then 4 and 39,091,323.25 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 | 156,365,293 | |
| -1 | 156,365,293 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 37 | 161 | 259 | 851 | 5,957 | 26,249 | 183,743 | 603,727 | 971,213 | 4,226,089 | 6,798,491 | 22,337,899 | 156,365,293 |
| -1 | -7 | -23 | -37 | -161 | -259 | -851 | -5,957 | -26,249 | -183,743 | -603,727 | -971,213 | -4,226,089 | -6,798,491 | -22,337,899 | -156,365,293 |
