HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 514, 544 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 663, 514, 544 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 663, 514, 544 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 663, 514, 544 is 1.
HCF(663, 514, 544) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 663, 514, 544 is 1.
Step 1: Since 663 > 514, we apply the division lemma to 663 and 514, to get
663 = 514 x 1 + 149
Step 2: Since the reminder 514 ≠ 0, we apply division lemma to 149 and 514, to get
514 = 149 x 3 + 67
Step 3: We consider the new divisor 149 and the new remainder 67, and apply the division lemma to get
149 = 67 x 2 + 15
We consider the new divisor 67 and the new remainder 15,and apply the division lemma to get
67 = 15 x 4 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 663 and 514 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(67,15) = HCF(149,67) = HCF(514,149) = HCF(663,514) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 544 > 1, we apply the division lemma to 544 and 1, to get
544 = 1 x 544 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 544 is 1
Notice that 1 = HCF(544,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 663, 514, 544?
Answer: HCF of 663, 514, 544 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 663, 514, 544 using Euclid's Algorithm?
Answer: For arbitrary numbers 663, 514, 544 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
