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 156,377,023, 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 | 156,377,023 | |
| -1 | -156,377,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 156,377,023.
Example:
1 x 156,377,023 = 156,377,023
and
-1 x -156,377,023 = 156,377,023
Notice both answers equal 156,377,023
With that explanation out of the way, let's continue. Next, we take the number 156,377,023 and divide it by 2:
156,377,023 ÷ 2 = 78,188,511.5
If the quotient is a whole number, then 2 and 78,188,511.5 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 | 156,377,023 | |
| -1 | -156,377,023 |
Now, we try dividing 156,377,023 by 3:
156,377,023 ÷ 3 = 52,125,674.3333
If the quotient is a whole number, then 3 and 52,125,674.3333 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 | 156,377,023 | |
| -1 | -156,377,023 |
Let's try dividing by 4:
156,377,023 ÷ 4 = 39,094,255.75
If the quotient is a whole number, then 4 and 39,094,255.75 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 | 156,377,023 | |
| -1 | 156,377,023 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 73 | 253 | 803 | 1,679 | 8,467 | 18,469 | 93,137 | 194,741 | 618,091 | 2,142,151 | 6,799,001 | 14,216,093 | 156,377,023 |
| -1 | -11 | -23 | -73 | -253 | -803 | -1,679 | -8,467 | -18,469 | -93,137 | -194,741 | -618,091 | -2,142,151 | -6,799,001 | -14,216,093 | -156,377,023 |
