Step 3: Find the highest factor in the common factors which is HCF.

Therefore, the HCF of 24 and 32 using the listing method are as follows: **Step 1: **Find the factors 24 and 32.

The factor of 24= 1,2,3,4,6,8,12 and 24

The factor of 32=1,2,4,8,16 and 32**Step 2: **Write the common factors

**HCF of 24 and 32 Using Prime Factorization Method**

**Step 1:** Find the prime factors for the given numbers

The prime factor of 24 = 2✕2✕2The prime factor of 32 =2✕2✕2✕2✕2**Step 2: **Find the common prime factors of the given number

The common prime factors in the given number are 2✕2✕2**Step 3: **Find the highest prime number. Which is the HCF of the given number.

The highest prime number = 8

Hence, the HCF of (6,12)=8.

**HCF of 24 and 32 Using Division Method**

In the division method, the following step is considered to know the HCF of the given numbers.**Step 1:** For the given numbers divide the smallest number by the largest number.**Step 2:** Continue the division with the quotient and the remainder until it achieves zero**Step 3: **once zero is reached the last divisor in which it was attained is the HCF of the given numbers.

Therefore, the HCF for 24 and 32 using the division method: **Step 1: **For the given numbers divide the smallest number by the largest number.**Step 2: **Continue the division with the quotient and the remainder until it achieves zero**Step 3: **once zero is reached the last divisor in which it was attained is the HCF of the given numbers.

The last divisor is 8

Hence, the HCF of (24,32)=8
