HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 941, 669, 806 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 941, 669, 806 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 941, 669, 806 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 941, 669, 806 is 1.
HCF(941, 669, 806) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 941, 669, 806 is 1.
Step 1: Since 941 > 669, we apply the division lemma to 941 and 669, to get
941 = 669 x 1 + 272
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 272 and 669, to get
669 = 272 x 2 + 125
Step 3: We consider the new divisor 272 and the new remainder 125, and apply the division lemma to get
272 = 125 x 2 + 22
We consider the new divisor 125 and the new remainder 22,and apply the division lemma to get
125 = 22 x 5 + 15
We consider the new divisor 22 and the new remainder 15,and apply the division lemma to get
22 = 15 x 1 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 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 941 and 669 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(125,22) = HCF(272,125) = HCF(669,272) = HCF(941,669) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 806 > 1, we apply the division lemma to 806 and 1, to get
806 = 1 x 806 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 806 is 1
Notice that 1 = HCF(806,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 941, 669, 806?
Answer: HCF of 941, 669, 806 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 941, 669, 806 using Euclid's Algorithm?
Answer: For arbitrary numbers 941, 669, 806 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
