Want to know how to use Euclid’s algorithm to find the HCF of 78, 88, 98, 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 78, 88, 98, 108 using Euclid's algorithm i.e 2 quickly.
Detailed Method to Find the HCF of 78,88,98,108 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 78,88,98,108. This is how to do it.
Step 1: The first step is to use the division lemma with 88 and 78 because 88 is greater than 78
88 = 78 x 1 + 10
Step 2: Here, the reminder 78 is not 0, we must use division lemma to 10 and 78, to get
78 = 10 x 7 + 8
Step 3: We consider the new divisor 10 and the new remainder 8, and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 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 2.Therefore, the HCF of 78 and 88 is equal to 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(78,10) = HCF(88,78) .
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 98 and 2 because 98 is greater than 2
98 = 2 x 49 + 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 2.Therefore, the HCF of 2 and 98 is equal to 2
Notice that 2 = HCF(98,2) .
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 2 because 108 is greater than 2
108 = 2 x 54 + 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 2.Therefore, the HCF of 2 and 108 is equal to 2
Notice that 2 = HCF(108,2) .
Result
Hence, the HCF of 78, 88, 98, 108 is equal to 2.
