HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 941, 191 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 941, 191 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 820, 941, 191 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 820, 941, 191 is 1.
HCF(820, 941, 191) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 941, 191 is 1.
Step 1: Since 941 > 820, we apply the division lemma to 941 and 820, to get
941 = 820 x 1 + 121
Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 121 and 820, to get
820 = 121 x 6 + 94
Step 3: We consider the new divisor 121 and the new remainder 94, and apply the division lemma to get
121 = 94 x 1 + 27
We consider the new divisor 94 and the new remainder 27,and apply the division lemma to get
94 = 27 x 3 + 13
We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get
27 = 13 x 2 + 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 820 and 941 is 1
Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(94,27) = HCF(121,94) = HCF(820,121) = HCF(941,820) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 191 > 1, we apply the division lemma to 191 and 1, to get
191 = 1 x 191 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 191 is 1
Notice that 1 = HCF(191,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 820, 941, 191?
Answer: HCF of 820, 941, 191 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 820, 941, 191 using Euclid's Algorithm?
Answer: For arbitrary numbers 820, 941, 191 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
