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 274,554,445, 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 | 274,554,445 | |
| -1 | -274,554,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 274,554,445.
Example:
1 x 274,554,445 = 274,554,445
and
-1 x -274,554,445 = 274,554,445
Notice both answers equal 274,554,445
With that explanation out of the way, let's continue. Next, we take the number 274,554,445 and divide it by 2:
274,554,445 ÷ 2 = 137,277,222.5
If the quotient is a whole number, then 2 and 137,277,222.5 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 | 274,554,445 | |
| -1 | -274,554,445 |
Now, we try dividing 274,554,445 by 3:
274,554,445 ÷ 3 = 91,518,148.3333
If the quotient is a whole number, then 3 and 91,518,148.3333 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 | 274,554,445 | |
| -1 | -274,554,445 |
Let's try dividing by 4:
274,554,445 ÷ 4 = 68,638,611.25
If the quotient is a whole number, then 4 and 68,638,611.25 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 | 274,554,445 | |
| -1 | 274,554,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 121 | 155 | 341 | 605 | 1,705 | 3,751 | 14,639 | 18,755 | 73,195 | 161,029 | 453,809 | 805,145 | 1,771,319 | 2,269,045 | 4,991,899 | 8,856,595 | 24,959,495 | 54,910,889 | 274,554,445 |
| -1 | -5 | -11 | -31 | -55 | -121 | -155 | -341 | -605 | -1,705 | -3,751 | -14,639 | -18,755 | -73,195 | -161,029 | -453,809 | -805,145 | -1,771,319 | -2,269,045 | -4,991,899 | -8,856,595 | -24,959,495 | -54,910,889 | -274,554,445 |
