HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 528, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 641, 528, 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 641, 528, 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 641, 528, 571 is 1.
HCF(641, 528, 571) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 641, 528, 571 is 1.
Step 1: Since 641 > 528, we apply the division lemma to 641 and 528, to get
641 = 528 x 1 + 113
Step 2: Since the reminder 528 ≠ 0, we apply division lemma to 113 and 528, to get
528 = 113 x 4 + 76
Step 3: We consider the new divisor 113 and the new remainder 76, and apply the division lemma to get
113 = 76 x 1 + 37
We consider the new divisor 76 and the new remainder 37,and apply the division lemma to get
76 = 37 x 2 + 2
We consider the new divisor 37 and the new remainder 2,and apply the division lemma to get
37 = 2 x 18 + 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 641 and 528 is 1
Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(76,37) = HCF(113,76) = HCF(528,113) = HCF(641,528) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 571 > 1, we apply the division lemma to 571 and 1, to get
571 = 1 x 571 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 571 is 1
Notice that 1 = HCF(571,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 641, 528, 571?
Answer: HCF of 641, 528, 571 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 641, 528, 571 using Euclid's Algorithm?
Answer: For arbitrary numbers 641, 528, 571 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
