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 741,365,155, 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 | 741,365,155 | |
| -1 | -741,365,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 741,365,155.
Example:
1 x 741,365,155 = 741,365,155
and
-1 x -741,365,155 = 741,365,155
Notice both answers equal 741,365,155
With that explanation out of the way, let's continue. Next, we take the number 741,365,155 and divide it by 2:
741,365,155 ÷ 2 = 370,682,577.5
If the quotient is a whole number, then 2 and 370,682,577.5 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 | 741,365,155 | |
| -1 | -741,365,155 |
Now, we try dividing 741,365,155 by 3:
741,365,155 ÷ 3 = 247,121,718.3333
If the quotient is a whole number, then 3 and 247,121,718.3333 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 | 741,365,155 | |
| -1 | -741,365,155 |
Let's try dividing by 4:
741,365,155 ÷ 4 = 185,341,288.75
If the quotient is a whole number, then 4 and 185,341,288.75 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 | 741,365,155 | |
| -1 | 741,365,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 527 | 2,635 | 281,353 | 1,406,765 | 4,783,001 | 8,721,943 | 23,915,005 | 43,609,715 | 148,273,031 | 741,365,155 |
| -1 | -5 | -17 | -31 | -85 | -155 | -527 | -2,635 | -281,353 | -1,406,765 | -4,783,001 | -8,721,943 | -23,915,005 | -43,609,715 | -148,273,031 | -741,365,155 |
