HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 962, 397, 22 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 962, 397, 22 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 962, 397, 22 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 962, 397, 22 is 1.
HCF(962, 397, 22) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 962, 397, 22 is 1.
Step 1: Since 962 > 397, we apply the division lemma to 962 and 397, to get
962 = 397 x 2 + 168
Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 168 and 397, to get
397 = 168 x 2 + 61
Step 3: We consider the new divisor 168 and the new remainder 61, and apply the division lemma to get
168 = 61 x 2 + 46
We consider the new divisor 61 and the new remainder 46,and apply the division lemma to get
61 = 46 x 1 + 15
We consider the new divisor 46 and the new remainder 15,and apply the division lemma to get
46 = 15 x 3 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 962 and 397 is 1
Notice that 1 = HCF(15,1) = HCF(46,15) = HCF(61,46) = HCF(168,61) = HCF(397,168) = HCF(962,397) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1
Notice that 1 = HCF(22,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 962, 397, 22?
Answer: HCF of 962, 397, 22 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 962, 397, 22 using Euclid's Algorithm?
Answer: For arbitrary numbers 962, 397, 22 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
