HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 538, 766 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 865, 538, 766 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 865, 538, 766 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 865, 538, 766 is 1.
HCF(865, 538, 766) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 865, 538, 766 is 1.
Step 1: Since 865 > 538, we apply the division lemma to 865 and 538, to get
865 = 538 x 1 + 327
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 327 and 538, to get
538 = 327 x 1 + 211
Step 3: We consider the new divisor 327 and the new remainder 211, and apply the division lemma to get
327 = 211 x 1 + 116
We consider the new divisor 211 and the new remainder 116,and apply the division lemma to get
211 = 116 x 1 + 95
We consider the new divisor 116 and the new remainder 95,and apply the division lemma to get
116 = 95 x 1 + 21
We consider the new divisor 95 and the new remainder 21,and apply the division lemma to get
95 = 21 x 4 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 865 and 538 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(95,21) = HCF(116,95) = HCF(211,116) = HCF(327,211) = HCF(538,327) = HCF(865,538) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 766 > 1, we apply the division lemma to 766 and 1, to get
766 = 1 x 766 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 766 is 1
Notice that 1 = HCF(766,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 865, 538, 766?
Answer: HCF of 865, 538, 766 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 865, 538, 766 using Euclid's Algorithm?
