Want to know how to use Euclid’s algorithm to find the HCF of 33, 11, 70, 23 ? 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 33, 11, 70, 23 using Euclid's algorithm i.e 1 quickly.
Detailed Method to Find the HCF of 33,11,70,23 using Euclid's algorithm
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 33,11,70,23. This is how to do it.
Step 1: The first step is to use the division lemma with 33 and 11 because 33 is greater than 11
33 = 11 x 3 + 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 11.Therefore, the HCF of 33 and 11 is equal to 11
Notice that 11 = HCF(33,11) .
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 70 and 11 because 70 is greater than 11
70 = 11 x 6 + 4
Step 2: Here, the reminder 11 is not 0, we must use division lemma to 4 and 11, to get
11 = 4 x 2 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 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 1.Therefore, the HCF of 11 and 70 is equal to 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(70,11) .
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 23 and 1 because 23 is greater than 1
23 = 1 x 23 + 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 1.Therefore, the HCF of 1 and 23 is equal to 1
Notice that 1 = HCF(23,1) .
Result
Hence, the HCF of 33, 11, 70, 23 is equal to 1.
