Factors by Division Method
To calculate the factors of 81, start by dividing the numbers by the smallest prime number, which is 2. If the number is not divisible by 2, proceed to the next prime number, such as 3, 5, 7, 11, 13, and continue this process until you reach 1.
Step 1: 81 ÷ 3 = 27
Step 2: 27 ÷ 3 = 9
Step 3: 9 ÷ 3 = 3
Step 4: 3 ÷ 3 = 1
In step 4, we have reached to 1, and so, the process is stopped.
• Prime Factors of 81:
• Prime Factorization of 81:
The factors will be all the multiples of 1, 3, 3, 3, 3, 9, 27, 81
Calculating all the factors:
3 = 1 x 3
9 = 1 x 9
27 = 1 x 27
81 = 1 x 81
Finally Factors of 81 = 1, 3, 9, 27, 81
