HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 858, 67 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 858, 67 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 819, 858, 67 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 819, 858, 67 is 1.
HCF(819, 858, 67) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 858, 67 is 1.
Step 1: Since 858 > 819, we apply the division lemma to 858 and 819, to get
858 = 819 x 1 + 39
Step 2: Since the reminder 819 ≠ 0, we apply division lemma to 39 and 819, to get
819 = 39 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 819 and 858 is 39
Notice that 39 = HCF(819,39) = HCF(858,819) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 67 > 39, we apply the division lemma to 67 and 39, to get
67 = 39 x 1 + 28
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 28 and 39, to get
39 = 28 x 1 + 11
Step 3: We consider the new divisor 28 and the new remainder 11, and apply the division lemma to get
28 = 11 x 2 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 39 and 67 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(28,11) = HCF(39,28) = HCF(67,39) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 819, 858, 67?
Answer: HCF of 819, 858, 67 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 819, 858, 67 using Euclid's Algorithm?
Answer: For arbitrary numbers 819, 858, 67 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
