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 361,274,543, 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 | 361,274,543 | |
-1 | -361,274,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 361,274,543.
Example:
1 x 361,274,543 = 361,274,543
and
-1 x -361,274,543 = 361,274,543
Notice both answers equal 361,274,543
With that explanation out of the way, let's continue. Next, we take the number 361,274,543 and divide it by 2:
361,274,543 ÷ 2 = 180,637,271.5
If the quotient is a whole number, then 2 and 180,637,271.5 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 | 361,274,543 | |
-1 | -361,274,543 |
Now, we try dividing 361,274,543 by 3:
361,274,543 ÷ 3 = 120,424,847.6667
If the quotient is a whole number, then 3 and 120,424,847.6667 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 | 361,274,543 | |
-1 | -361,274,543 |
Let's try dividing by 4:
361,274,543 ÷ 4 = 90,318,635.75
If the quotient is a whole number, then 4 and 90,318,635.75 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 | 361,274,543 | |
-1 | 361,274,543 |
If you did it right, you will end up with this table:
1 | 7 | 51,610,649 | 361,274,543 |
-1 | -7 | -51,610,649 | -361,274,543 |
