How to find HCF of 26 and 91

Below are some of the methods of finding HCF of 26 and 91 by:

• Prime Factorization Method
• Listing Common Factors
• Long Division Method

HCF of 26 and 91 by Prime Factorization Method

Follow the below-given steps to find the HCF of numbers using the prime factorization method.

• Write each number as a product of prime factors. This method is called prime factorization.
• Now write the common factors of the two numbers
• The product of all common prime factors is the HCF

The prime factor of 26 and 91, respectively, are,

• 26 = 2 × 13
• 91 = 7 × 13

Since 13 is the largest and only common prime factor of 26 and 91

HCF(26, 91) = 13

HCF of 26 and 91 by Listing Common Factor

Listing Common Factor means identifying the numbers that can evenly divide two or more numbers.

By listing common factor of 26 and 91 we can start by listing the factors of each number:

• Factor of 26: 1, 2, 13, 26
• Factor of 91: 1, 7, 13, 91

Since 13 is the highest common factor among 26 and 91

Hence, HCF of 26 and 91 is 13

HCF of 26 and 91 by Long Division

Below are the steps for finding HCF of 26 and 91 by Long Division method:

• Divide the larger number by the smaller one.
• Replace the larger number with the smaller one and the smaller number with the Remainder.
• Repeat step 1 and 2 until we get a remainder of 0.

91 ÷ 26, Q = 3, R = 13

26 ÷ 13, Q = 2, R = 0

Therefore, HCF = 13

Solved Example on HCF of 26 and 91

Below are some of the solved examples on HCF of 26 and 91

Example 1: If the product of two numbers = 2366 and HCF = 13, find the LCM?

Solution:

We know, LCM × HCF = product of numbers

LCM = Product/HCF = 2366/13

Therefore, the LCM is 182.

Example 2: Find the highest number that divides 26 and 91 exactly.

Solution:

The highest number that divides 26 and 91 exactly is their HCF.

26 = 2 × 13

91 = 7 × 13

HCF (26, 91) = 13

Example 3: For two numbers, HCF = 10 and LCM = 92. If one number is 92, find the other number.

Solution:

HCF × LCM = 92 × x

⇒ x = (HCF × LCM)/92

⇒ x = (10 × 92)/92

⇒ x = 10
