HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 618, 491, 326 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 618, 491, 326 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 618, 491, 326 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 618, 491, 326 is 1.
HCF(618, 491, 326) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 618, 491, 326 is 1.
Step 1: Since 618 > 491, we apply the division lemma to 618 and 491, to get
618 = 491 x 1 + 127
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 127 and 491, to get
491 = 127 x 3 + 110
Step 3: We consider the new divisor 127 and the new remainder 110, and apply the division lemma to get
127 = 110 x 1 + 17
We consider the new divisor 110 and the new remainder 17,and apply the division lemma to get
110 = 17 x 6 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 618 and 491 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(110,17) = HCF(127,110) = HCF(491,127) = HCF(618,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 326 > 1, we apply the division lemma to 326 and 1, to get
326 = 1 x 326 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 326 is 1
Notice that 1 = HCF(326,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 618, 491, 326?
Answer: HCF of 618, 491, 326 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 618, 491, 326 using Euclid's Algorithm?
Answer: For arbitrary numbers 618, 491, 326 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
