Want to know how to use Euclid’s algorithm to find the HCF of 49, 62, 80, 117 ? 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 49, 62, 80, 117 using Euclid's algorithm i.e 1 quickly.
Detailed Method to Find the HCF of 49,62,80,117 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 49,62,80,117. This is how to do it.
Step 1: The first step is to use the division lemma with 62 and 49 because 62 is greater than 49
62 = 49 x 1 + 13
Step 2: Since the reminder 49 is not 0, we must use division lemma to 13 and 49, to get
49 = 13 x 3 + 10
Step 3: We consider the new divisor 13 and the new remainder 10, and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 49 and 62 is equal to 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(49,13) = HCF(62,49) .
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 80 and 1 because 80 is greater than 1
80 = 1 x 80 + 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 80 is equal to 1
Notice that 1 = HCF(80,1) .
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 117 and 1 because 117 is greater than 1
117 = 1 x 117 + 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 117 is equal to 1
Notice that 1 = HCF(117,1) .
Result
Hence, the HCF of 49, 62, 80, 117 is equal to 1.
