HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 359, 630 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 359, 630 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 863, 359, 630 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 863, 359, 630 is 1.
HCF(863, 359, 630) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 359, 630 is 1.
Step 1: Since 863 > 359, we apply the division lemma to 863 and 359, to get
863 = 359 x 2 + 145
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 145 and 359, to get
359 = 145 x 2 + 69
Step 3: We consider the new divisor 145 and the new remainder 69, and apply the division lemma to get
145 = 69 x 2 + 7
We consider the new divisor 69 and the new remainder 7,and apply the division lemma to get
69 = 7 x 9 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 359 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(69,7) = HCF(145,69) = HCF(359,145) = HCF(863,359) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 630 > 1, we apply the division lemma to 630 and 1, to get
630 = 1 x 630 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 630 is 1
Notice that 1 = HCF(630,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 863, 359, 630?
Answer: HCF of 863, 359, 630 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 863, 359, 630 using Euclid's Algorithm?
Answer: For arbitrary numbers 863, 359, 630 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
