HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 203, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 667, 203, 805 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 667, 203, 805 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 667, 203, 805 is 1.
HCF(667, 203, 805) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 667, 203, 805 is 1.
Step 1: Since 667 > 203, we apply the division lemma to 667 and 203, to get
667 = 203 x 3 + 58
Step 2: Since the reminder 203 ≠ 0, we apply division lemma to 58 and 203, to get
203 = 58 x 3 + 29
Step 3: We consider the new divisor 58 and the new remainder 29, and apply the division lemma to get
58 = 29 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 29, the HCF of 667 and 203 is 29
Notice that 29 = HCF(58,29) = HCF(203,58) = HCF(667,203) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 805 > 29, we apply the division lemma to 805 and 29, to get
805 = 29 x 27 + 22
Step 2: Since the reminder 29 ≠ 0, we apply division lemma to 22 and 29, to get
29 = 22 x 1 + 7
Step 3: We consider the new divisor 22 and the new remainder 7, and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 29 and 805 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(29,22) = HCF(805,29) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 667, 203, 805?
Answer: HCF of 667, 203, 805 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 667, 203, 805 using Euclid's Algorithm?
Answer: For arbitrary numbers 667, 203, 805 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
