HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 283, 424 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 471, 283, 424 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 471, 283, 424 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 471, 283, 424 is 1.
HCF(471, 283, 424) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 471, 283, 424 is 1.
Step 1: Since 471 > 283, we apply the division lemma to 471 and 283, to get
471 = 283 x 1 + 188
Step 2: Since the reminder 283 ≠ 0, we apply division lemma to 188 and 283, to get
283 = 188 x 1 + 95
Step 3: We consider the new divisor 188 and the new remainder 95, and apply the division lemma to get
188 = 95 x 1 + 93
We consider the new divisor 95 and the new remainder 93,and apply the division lemma to get
95 = 93 x 1 + 2
We consider the new divisor 93 and the new remainder 2,and apply the division lemma to get
93 = 2 x 46 + 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 471 and 283 is 1
Notice that 1 = HCF(2,1) = HCF(93,2) = HCF(95,93) = HCF(188,95) = HCF(283,188) = HCF(471,283) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 424 > 1, we apply the division lemma to 424 and 1, to get
424 = 1 x 424 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 424 is 1
Notice that 1 = HCF(424,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 471, 283, 424?
Answer: HCF of 471, 283, 424 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 471, 283, 424 using Euclid's Algorithm?
Answer: For arbitrary numbers 471, 283, 424 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
