HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 481, 669 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 481, 669 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 805, 481, 669 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 805, 481, 669 is 1.
HCF(805, 481, 669) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 805, 481, 669 is 1.
Step 1: Since 805 > 481, we apply the division lemma to 805 and 481, to get
805 = 481 x 1 + 324
Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 324 and 481, to get
481 = 324 x 1 + 157
Step 3: We consider the new divisor 324 and the new remainder 157, and apply the division lemma to get
324 = 157 x 2 + 10
We consider the new divisor 157 and the new remainder 10,and apply the division lemma to get
157 = 10 x 15 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 805 and 481 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(157,10) = HCF(324,157) = HCF(481,324) = HCF(805,481) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 669 > 1, we apply the division lemma to 669 and 1, to get
669 = 1 x 669 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 669 is 1
Notice that 1 = HCF(669,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 805, 481, 669?
Answer: HCF of 805, 481, 669 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 805, 481, 669 using Euclid's Algorithm?
Answer: For arbitrary numbers 805, 481, 669 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
