Detailed Steps for Finding HCF of Three Numbers Using Factoring Method

• In the initial step, find out the list of all factors for each number to solve the Highest common factor.
• These factors divide the given numbers evenly with zero remainders.
• Later, list out the common factors and consider the largest common factor as HCF of three numbers.

Example:

Find the HCF of 80, 45, 32 using Factoring?

Solution:

Given numbers are 80, 45, 32 and find the factors for each number initially,

The factors of 32 are 1, 2, 4, 8, 16, 32

The factors of 45 are 1, 3, 5, 9, 15, 45

The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

Now, list the common factors from each number, there is only one common factor for all three numbers ie., 1.

Thus, HCF(80, 45, 32) is 1.

Highest Common Factor of 3 Numbers by Prime Factorization Method

The steps that are involved in finding the highest common factor of three numbers using prime factorization are listed here:

• First and foremost, you need to find the prime factors of each of the three numbers.
• Later, identify the common prime factors of the 3 numbers
• Next, multiply the highest occurrence of common factors.
• Finally, the result of the common factors multiplication is the Highest Common Factor of the three numbers.

Example:

Find HCF(36, 27, 80) by Prime Factorization?

Solution:

Given three numbers to find HCF are 36, 27, and 80

Step 1: Find the product of prime factors for each given number.

Prime factors of 36 = 2² × 3²

Prime factors of 27 = 3³

Prime factors of 80 = 2⁴ × 5

Step 2: HCF is the product of all common prime factors using the least power of each common prime factor. Here there are no common prime factors for the given numbers.

So, the answer for HCF of three numbers 36, 27, and 80 is 1.

Procedure on HCF of 3 Numbers using Division Method

A Division Method is also one of the best methods to solve the Highest common factor of three numbers. For three numbers, first, we need to calculate the HCF using the division method for two numbers then again HCF of two numbers result and the third number. The steps to find out HCF of two given numbers using the division method are as follows:

• Initially, take a large number as a dividend and a small number as a divisor.
• Now, Divide the larger number by the smaller number.
• If the remainder is not zero then the divisor of step 1 is divided by its remainder.
• Repeat the process till we get the zero as the remainder.
• Finally, the last divisor is the HCF of two numbers.
• Now, find out the HCF of two numbers and left third numbers using the division method to get the result for HCF of given three numbers.
• Take the HCF of two numbers result and third number and repeat the process as we did for finding the HCF of two numbers
• The final divisor after calculating the whole process is considered as the Highest common factor of three numbers.

Example:

Find the HCF of 9, 27, and 48 using the division method?

Solution:

Given three numbers are 9, 27, 48

Now take two numbers first for finding the HCF of two numbers

Let's first, find out HCF of 9 and 27 by division method,

Thus, HCF of 9 and 27 = 9

Now, find out HCF of 9, 27, and 48

⇒ HCF of [(HCF of 9, 27) and 48]

⇒ HCF of (9, 48)

Apply the division method steps and find out the HCF of 9 and 48

So, the answer for HCF of 9, 27, 48 is 3.
