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 156,153,335, 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 | 156,153,335 | |
| -1 | -156,153,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,153,335.
Example:
1 x 156,153,335 = 156,153,335
and
-1 x -156,153,335 = 156,153,335
Notice both answers equal 156,153,335
With that explanation out of the way, let's continue. Next, we take the number 156,153,335 and divide it by 2:
156,153,335 ÷ 2 = 78,076,667.5
If the quotient is a whole number, then 2 and 78,076,667.5 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 | 156,153,335 | |
| -1 | -156,153,335 |
Now, we try dividing 156,153,335 by 3:
156,153,335 ÷ 3 = 52,051,111.6667
If the quotient is a whole number, then 3 and 52,051,111.6667 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 | 156,153,335 | |
| -1 | -156,153,335 |
Let's try dividing by 4:
156,153,335 ÷ 4 = 39,038,333.75
If the quotient is a whole number, then 4 and 39,038,333.75 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 | 156,153,335 | |
| -1 | 156,153,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 179 | 895 | 2,327 | 11,635 | 13,421 | 67,105 | 174,473 | 872,365 | 2,402,359 | 12,011,795 | 31,230,667 | 156,153,335 |
| -1 | -5 | -13 | -65 | -179 | -895 | -2,327 | -11,635 | -13,421 | -67,105 | -174,473 | -872,365 | -2,402,359 | -12,011,795 | -31,230,667 | -156,153,335 |
