HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 538, 971, 667 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 538, 971, 667 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 538, 971, 667 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 538, 971, 667 is 1.
HCF(538, 971, 667) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 538, 971, 667 is 1.
Step 1: Since 971 > 538, we apply the division lemma to 971 and 538, to get
971 = 538 x 1 + 433
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 433 and 538, to get
538 = 433 x 1 + 105
Step 3: We consider the new divisor 433 and the new remainder 105, and apply the division lemma to get
433 = 105 x 4 + 13
We consider the new divisor 105 and the new remainder 13,and apply the division lemma to get
105 = 13 x 8 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 538 and 971 is 1
Notice that 1 = HCF(13,1) = HCF(105,13) = HCF(433,105) = HCF(538,433) = HCF(971,538) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 667 > 1, we apply the division lemma to 667 and 1, to get
667 = 1 x 667 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 667 is 1
Notice that 1 = HCF(667,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 538, 971, 667?
Answer: HCF of 538, 971, 667 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 538, 971, 667 using Euclid's Algorithm?
Answer: For arbitrary numbers 538, 971, 667 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
