HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 531, 8666, 1749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 531, 8666, 1749 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 531, 8666, 1749 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 531, 8666, 1749 is 1.
HCF(531, 8666, 1749) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 531, 8666, 1749 is 1.
Step 1: Since 8666 > 531, we apply the division lemma to 8666 and 531, to get
8666 = 531 x 16 + 170
Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 170 and 531, to get
531 = 170 x 3 + 21
Step 3: We consider the new divisor 170 and the new remainder 21, and apply the division lemma to get
170 = 21 x 8 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 531 and 8666 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(170,21) = HCF(531,170) = HCF(8666,531) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1749 > 1, we apply the division lemma to 1749 and 1, to get
1749 = 1 x 1749 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1749 is 1
Notice that 1 = HCF(1749,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 531, 8666, 1749?
Answer: HCF of 531, 8666, 1749 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 531, 8666, 1749 using Euclid's Algorithm?
Answer: For arbitrary numbers 531, 8666, 1749 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
