HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 443, 797, 847 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 443, 797, 847 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 443, 797, 847 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 443, 797, 847 is 1.
HCF(443, 797, 847) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 443, 797, 847 is 1.
Step 1: Since 797 > 443, we apply the division lemma to 797 and 443, to get
797 = 443 x 1 + 354
Step 2: Since the reminder 443 ≠ 0, we apply division lemma to 354 and 443, to get
443 = 354 x 1 + 89
Step 3: We consider the new divisor 354 and the new remainder 89, and apply the division lemma to get
354 = 89 x 3 + 87
We consider the new divisor 89 and the new remainder 87,and apply the division lemma to get
89 = 87 x 1 + 2
We consider the new divisor 87 and the new remainder 2,and apply the division lemma to get
87 = 2 x 43 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 443 and 797 is 1
Notice that 1 = HCF(2,1) = HCF(87,2) = HCF(89,87) = HCF(354,89) = HCF(443,354) = HCF(797,443) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 847 > 1, we apply the division lemma to 847 and 1, to get
847 = 1 x 847 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 847 is 1
Notice that 1 = HCF(847,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 443, 797, 847?
Answer: HCF of 443, 797, 847 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 443, 797, 847 using Euclid's Algorithm?
Answer: For arbitrary numbers 443, 797, 847 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
