HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 834, 995, 646 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 834, 995, 646 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 834, 995, 646 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 834, 995, 646 is 1.
HCF(834, 995, 646) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 834, 995, 646 is 1.
Step 1: Since 995 > 834, we apply the division lemma to 995 and 834, to get
995 = 834 x 1 + 161
Step 2: Since the reminder 834 ≠ 0, we apply division lemma to 161 and 834, to get
834 = 161 x 5 + 29
Step 3: We consider the new divisor 161 and the new remainder 29, and apply the division lemma to get
161 = 29 x 5 + 16
We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get
29 = 16 x 1 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 834 and 995 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(161,29) = HCF(834,161) = HCF(995,834) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 646 > 1, we apply the division lemma to 646 and 1, to get
646 = 1 x 646 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 646 is 1
Notice that 1 = HCF(646,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 834, 995, 646?
Answer: HCF of 834, 995, 646 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 834, 995, 646 using Euclid's Algorithm?
Answer: For arbitrary numbers 834, 995, 646 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
