HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 620, 627 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 620, 627 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 486, 620, 627 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 486, 620, 627 is 1.
HCF(486, 620, 627) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 620, 627 is 1.
Step 1: Since 620 > 486, we apply the division lemma to 620 and 486, to get
620 = 486 x 1 + 134
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 134 and 486, to get
486 = 134 x 3 + 84
Step 3: We consider the new divisor 134 and the new remainder 84, and apply the division lemma to get
134 = 84 x 1 + 50
We consider the new divisor 84 and the new remainder 50,and apply the division lemma to get
84 = 50 x 1 + 34
We consider the new divisor 50 and the new remainder 34,and apply the division lemma to get
50 = 34 x 1 + 16
We consider the new divisor 34 and the new remainder 16,and apply the division lemma to get
34 = 16 x 2 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 486 and 620 is 2
Notice that 2 = HCF(16,2) = HCF(34,16) = HCF(50,34) = HCF(84,50) = HCF(134,84) = HCF(486,134) = HCF(620,486) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 627 > 2, we apply the division lemma to 627 and 2, to get
627 = 2 x 313 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 627 is 1
Notice that 1 = HCF(2,1) = HCF(627,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 486, 620, 627?
Answer: HCF of 486, 620, 627 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 486, 620, 627 using Euclid's Algorithm?
Answer: For arbitrary numbers 486, 620, 627 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
