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 156,629,395, 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 | 156,629,395 | |
| -1 | -156,629,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,629,395.
Example:
1 x 156,629,395 = 156,629,395
and
-1 x -156,629,395 = 156,629,395
Notice both answers equal 156,629,395
With that explanation out of the way, let's continue. Next, we take the number 156,629,395 and divide it by 2:
156,629,395 ÷ 2 = 78,314,697.5
If the quotient is a whole number, then 2 and 78,314,697.5 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 | 156,629,395 | |
| -1 | -156,629,395 |
Now, we try dividing 156,629,395 by 3:
156,629,395 ÷ 3 = 52,209,798.3333
If the quotient is a whole number, then 3 and 52,209,798.3333 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 | 156,629,395 | |
| -1 | -156,629,395 |
Let's try dividing by 4:
156,629,395 ÷ 4 = 39,157,348.75
If the quotient is a whole number, then 4 and 39,157,348.75 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 | 156,629,395 | |
| -1 | 156,629,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 793 | 3,965 | 39,503 | 197,515 | 513,539 | 2,409,683 | 2,567,695 | 12,048,415 | 31,325,879 | 156,629,395 |
| -1 | -5 | -13 | -61 | -65 | -305 | -793 | -3,965 | -39,503 | -197,515 | -513,539 | -2,409,683 | -2,567,695 | -12,048,415 | -31,325,879 | -156,629,395 |
