HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 402, 571 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 402, 571 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 402, 571 is 1.
HCF(402, 571) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 402, 571 is 1.
Step 1: Since 571 > 402, we apply the division lemma to 571 and 402, to get
571 = 402 x 1 + 169
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 169 and 402, to get
402 = 169 x 2 + 64
Step 3: We consider the new divisor 169 and the new remainder 64, and apply the division lemma to get
169 = 64 x 2 + 41
We consider the new divisor 64 and the new remainder 41,and apply the division lemma to get
64 = 41 x 1 + 23
We consider the new divisor 41 and the new remainder 23,and apply the division lemma to get
41 = 23 x 1 + 18
We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get
23 = 18 x 1 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 402 and 571 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(41,23) = HCF(64,41) = HCF(169,64) = HCF(402,169) = HCF(571,402) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 402, 571?
Answer: HCF of 402, 571 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 402, 571 using Euclid's Algorithm?
Answer: For arbitrary numbers 402, 571 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
