WebAll you have to do is list the multiplies of both of the numbers and look for the common number. Example: 5 and 6 5 = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 6 = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 The LMC of 5 and 6 is 30. Example: 10 and 12 10 = 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120 WebTo find the Highest Common Factor (HCF) and the Least Common Multiple (LCM) of two numbers, we use the prime factorization method. For this, we first do the prime factorization of both the numbers. The following points related to HCF and LCM need to be kept in mind: HCF is the product of the smallest power of each common prime factor.

WebFind the below steps in order to get the HCF of two positive integers a and b. Here a > b. Step 1: Applying Euclid’s division lemma to a and b we get two whole numbers q and r such that, a = bq+r ; 0 r < b. Step 2: If r = 0, then b is the HCF of a and b. If r ≠0, then apply Euclid’s division lemma to b and r. WebExample 2: Find the HCF of 126, 162, and 180 using the fundamental theorem of arithmetic. Solution: We will first find the prime factorization of 126, 162, and 180. Prime factors of 126 = 2 1 × 3 2 × 7 1. Prime factors of 162 = 2 1 × 3 4. Prime factors of 180 = 2 2 × 3 2 × 5 1.

WebSo in the above question, you need to find the HCF of 36, 45, and 72. But wait, do we know how to find HCF? Read further to know the three different techniques commonly used to find HCF. We will also look at a few of the important questions. How to find HCF. There are three ways to find HCF: By Prime Factorization Method WebHCF is the largest possible common factor, so it will divide both. LCM is the smallest possible multiple, so it can be divided by both of our numbers here. Let's say our numbers are 13 and 27 and we're asked to find out the LCM and HCF. If you use the traditional method to find out the HCF by prime factorisation, you'll find that the HCF is 1.

Answer: GCF = 4 for the values 8, 12, 20 Solution … WebApr 8, 2024 · As we know, the two numbers which have only 1 as their common factor are known as co-primes. For example, Factors of 5 are 1 and 5. Factors of 3 are 1 and 3. Here, the common factor is 1. Thus, 5 and 3 are the co-primes. Now, to find out the LCM of two or more numbers using the factorization method, we have to find their factors.

WebConsider we have numbers 87, 156 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b. Highest common factor (HCF) of 87, 156 is 3. HCF(87, 156) = 3.

WebFirstly, let us find the HCF of 468 and 222. By Euclid's Division Algorithm, we have 468=222 (2)+24. 222=24 (9)+6 24=6 (4)+0 We know that the HCF is the remainder in the second last step. Thus, HCF (468,222)= 6. Now, from the second step of Euclid's Division Algorithm, we can rearrange the equation to isolate 6, 6= 222− (24×9).
