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 155,426,341, 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 | 155,426,341 | |
| -1 | -155,426,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,426,341.
Example:
1 x 155,426,341 = 155,426,341
and
-1 x -155,426,341 = 155,426,341
Notice both answers equal 155,426,341
With that explanation out of the way, let's continue. Next, we take the number 155,426,341 and divide it by 2:
155,426,341 ÷ 2 = 77,713,170.5
If the quotient is a whole number, then 2 and 77,713,170.5 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 | 155,426,341 | |
| -1 | -155,426,341 |
Now, we try dividing 155,426,341 by 3:
155,426,341 ÷ 3 = 51,808,780.3333
If the quotient is a whole number, then 3 and 51,808,780.3333 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 | 155,426,341 | |
| -1 | -155,426,341 |
Let's try dividing by 4:
155,426,341 ÷ 4 = 38,856,585.25
If the quotient is a whole number, then 4 and 38,856,585.25 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 | 155,426,341 | |
| -1 | 155,426,341 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 33,289 | 233,023 | 765,647 | 965,381 | 5,359,529 | 6,757,667 | 22,203,763 | 155,426,341 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -33,289 | -233,023 | -765,647 | -965,381 | -5,359,529 | -6,757,667 | -22,203,763 | -155,426,341 |
