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 354,320,743, 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 | 354,320,743 | |
| -1 | -354,320,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 354,320,743.
Example:
1 x 354,320,743 = 354,320,743
and
-1 x -354,320,743 = 354,320,743
Notice both answers equal 354,320,743
With that explanation out of the way, let's continue. Next, we take the number 354,320,743 and divide it by 2:
354,320,743 ÷ 2 = 177,160,371.5
If the quotient is a whole number, then 2 and 177,160,371.5 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 | 354,320,743 | |
| -1 | -354,320,743 |
Now, we try dividing 354,320,743 by 3:
354,320,743 ÷ 3 = 118,106,914.3333
If the quotient is a whole number, then 3 and 118,106,914.3333 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 | 354,320,743 | |
| -1 | -354,320,743 |
Let's try dividing by 4:
354,320,743 ÷ 4 = 88,580,185.75
If the quotient is a whole number, then 4 and 88,580,185.75 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 | 354,320,743 | |
| -1 | 354,320,743 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 497 | 613 | 1,163 | 4,291 | 8,141 | 43,523 | 82,573 | 304,661 | 578,011 | 712,919 | 4,990,433 | 50,617,249 | 354,320,743 |
| -1 | -7 | -71 | -497 | -613 | -1,163 | -4,291 | -8,141 | -43,523 | -82,573 | -304,661 | -578,011 | -712,919 | -4,990,433 | -50,617,249 | -354,320,743 |
