HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 301, 716 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 301, 716 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, 301, 716 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, 301, 716 is 1.
HCF(820, 301, 716) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 301, 716 is 1.
Step 1: Since 820 > 301, we apply the division lemma to 820 and 301, to get
820 = 301 x 2 + 218
Step 2: Since the reminder 301 ≠ 0, we apply division lemma to 218 and 301, to get
301 = 218 x 1 + 83
Step 3: We consider the new divisor 218 and the new remainder 83, and apply the division lemma to get
218 = 83 x 2 + 52
We consider the new divisor 83 and the new remainder 52,and apply the division lemma to get
83 = 52 x 1 + 31
We consider the new divisor 52 and the new remainder 31,and apply the division lemma to get
52 = 31 x 1 + 21
We consider the new divisor 31 and the new remainder 21,and apply the division lemma to get
31 = 21 x 1 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 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 820 and 301 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(31,21) = HCF(52,31) = HCF(83,52) = HCF(218,83) = HCF(301,218) = HCF(820,301) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 716 > 1, we apply the division lemma to 716 and 1, to get
716 = 1 x 716 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 716 is 1
Notice that 1 = HCF(716,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 820, 301, 716?
Answer: HCF of 820, 301, 716 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 820, 301, 716 using Euclid's Algorithm?
Answer: For arbitrary numbers 820, 301, 716 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
