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 155,767,345, 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 | 155,767,345 | |
| -1 | -155,767,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,767,345.
Example:
1 x 155,767,345 = 155,767,345
and
-1 x -155,767,345 = 155,767,345
Notice both answers equal 155,767,345
With that explanation out of the way, let's continue. Next, we take the number 155,767,345 and divide it by 2:
155,767,345 ÷ 2 = 77,883,672.5
If the quotient is a whole number, then 2 and 77,883,672.5 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 | 155,767,345 | |
| -1 | -155,767,345 |
Now, we try dividing 155,767,345 by 3:
155,767,345 ÷ 3 = 51,922,448.3333
If the quotient is a whole number, then 3 and 51,922,448.3333 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 | 155,767,345 | |
| -1 | -155,767,345 |
Let's try dividing by 4:
155,767,345 ÷ 4 = 38,941,836.25
If the quotient is a whole number, then 4 and 38,941,836.25 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 | 155,767,345 | |
| -1 | 155,767,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 83 | 85 | 415 | 1,411 | 7,055 | 22,079 | 110,395 | 375,343 | 1,832,557 | 1,876,715 | 9,162,785 | 31,153,469 | 155,767,345 |
| -1 | -5 | -17 | -83 | -85 | -415 | -1,411 | -7,055 | -22,079 | -110,395 | -375,343 | -1,832,557 | -1,876,715 | -9,162,785 | -31,153,469 | -155,767,345 |
