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 157,179,295, 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 | 157,179,295 | |
| -1 | -157,179,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 157,179,295.
Example:
1 x 157,179,295 = 157,179,295
and
-1 x -157,179,295 = 157,179,295
Notice both answers equal 157,179,295
With that explanation out of the way, let's continue. Next, we take the number 157,179,295 and divide it by 2:
157,179,295 ÷ 2 = 78,589,647.5
If the quotient is a whole number, then 2 and 78,589,647.5 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 | 157,179,295 | |
| -1 | -157,179,295 |
Now, we try dividing 157,179,295 by 3:
157,179,295 ÷ 3 = 52,393,098.3333
If the quotient is a whole number, then 3 and 52,393,098.3333 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 | 157,179,295 | |
| -1 | -157,179,295 |
Let's try dividing by 4:
157,179,295 ÷ 4 = 39,294,823.75
If the quotient is a whole number, then 4 and 39,294,823.75 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 | 157,179,295 | |
| -1 | 157,179,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 5,915 | 26,573 | 132,865 | 186,011 | 345,449 | 930,055 | 1,727,245 | 2,418,143 | 4,490,837 | 12,090,715 | 22,454,185 | 31,435,859 | 157,179,295 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -5,915 | -26,573 | -132,865 | -186,011 | -345,449 | -930,055 | -1,727,245 | -2,418,143 | -4,490,837 | -12,090,715 | -22,454,185 | -31,435,859 | -157,179,295 |
