Take the help of the HCF Calculator using the Euclid Division Algorithm which finds HCF of 64, 98, 78, 80 using Euclid's algorithm i.e 2 quickly.

Detailed Method to Find the HCF of 64,98,78,80 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 64,98,78,80. This is how to do it.

Step 1: The first step is to use the division lemma with 98 and 64 because 98 is greater than 64

98 = 64 x 1 + 34

Step 2: Since the reminder 64 is not 0, we must use division lemma to 34 and 64, to get

64 = 34 x 1 + 30

Step 3: We consider the new divisor 34 and the new remainder 30, and apply the division lemma to get

34 = 30 x 1 + 4

We consider the new divisor 30 and the new remainder 4,and apply the division lemma to get

30 = 4 x 7 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 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 2.Therefore, the HCF of 64 and 98 is equal to 2

Notice that 2 = HCF(4,2) = HCF(30,4) = HCF(34,30) = HCF(64,34) = HCF(98,64) .

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 78 and 2 because 78 is greater than 2

78 = 2 x 39 + 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 78 is equal to 2

Notice that 2 = HCF(78,2) .

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 80 and 2 because 80 is greater than 2

80 = 2 x 40 + 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 80 is equal to 2

Notice that 2 = HCF(80,2) .

Result

Hence, the HCF of 64, 98, 78, 80 is equal to 2.
