HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 767, 551, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 767, 551, 163 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 767, 551, 163 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 767, 551, 163 is 1.
HCF(767, 551, 163) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 767, 551, 163 is 1.
Step 1: Since 767 > 551, we apply the division lemma to 767 and 551, to get
767 = 551 x 1 + 216
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 216 and 551, to get
551 = 216 x 2 + 119
Step 3: We consider the new divisor 216 and the new remainder 119, and apply the division lemma to get
216 = 119 x 1 + 97
We consider the new divisor 119 and the new remainder 97,and apply the division lemma to get
119 = 97 x 1 + 22
We consider the new divisor 97 and the new remainder 22,and apply the division lemma to get
97 = 22 x 4 + 9
We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get
22 = 9 x 2 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 767 and 551 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(97,22) = HCF(119,97) = HCF(216,119) = HCF(551,216) = HCF(767,551) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 163 > 1, we apply the division lemma to 163 and 1, to get
163 = 1 x 163 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 163 is 1
Notice that 1 = HCF(163,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 767, 551, 163?
Answer: HCF of 767, 551, 163 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 767, 551, 163 using Euclid's Algorithm?
Answer: For arbitrary numbers 767, 551, 163 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
