Want to know how to use Euclid’s algorithm to find the HCF of 54, 90, 108 ? Well, you have come to the right place. In this article, you will be learning about Euclid’s algorithm and how to use it to calculate the HCF with ease.
Take the help of the HCF Calculator using the Euclid Division Algorithm which finds HCF of 54, 90, 108 using Euclid's algorithm i.e 18 quickly.
Euclid’s algorithm is written as a = bq + r. This is known as the division lemma. The variable r varies according to 0 ≤ r ≤ b. We can use this to figure out the HCF of 54,90,108. This is how to do it.
Step 1: The first step is to use the division lemma with 90 and 54 because 90 is greater than 54
90 = 54 x 1 + 36
Step 2: Here, the reminder 54 is not 0, we must use division lemma to 36 and 54, to get
54 = 36 x 1 + 18
Step 3: We consider the new divisor 36 and the new remainder 18, and apply the division lemma to get
36 = 18 x 2 + 0
As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 18.Therefore, the HCF of 54 and 90 is equal to 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(90,54) .
Now, we must treat the HCF of the first two numbers as the next number in our calculation, and next
Step 1: The first step is to use the division lemma with 108 and 18 because 108 is greater than 18
108 = 18 x 6 + 0
As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 18.Therefore, the HCF of 18 and 108 is equal to 18
Notice that 18 = HCF(108,18) .
Hence, the HCF of 54, 90, 108 is equal to 18.
