HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 772, 783, 698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 772, 783, 698 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, 772, 783, 698 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, 772, 783, 698 is 1.
HCF(863, 772, 783, 698) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 772, 783, 698 is 1.
Step 1: Since 863 > 772, we apply the division lemma to 863 and 772, to get
863 = 772 x 1 + 91
Step 2: Since the reminder 772 ≠ 0, we apply division lemma to 91 and 772, to get
772 = 91 x 8 + 44
Step 3: We consider the new divisor 91 and the new remainder 44, and apply the division lemma to get
91 = 44 x 2 + 3
We consider the new divisor 44 and the new remainder 3,and apply the division lemma to get
44 = 3 x 14 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 863 and 772 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(44,3) = HCF(91,44) = HCF(772,91) = HCF(863,772) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 783 > 1, we apply the division lemma to 783 and 1, to get
783 = 1 x 783 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 783 is 1
Notice that 1 = HCF(783,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 698 > 1, we apply the division lemma to 698 and 1, to get
698 = 1 x 698 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 698 is 1
Notice that 1 = HCF(698,1) .
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, 772, 783, 698?
Answer: HCF of 863, 772, 783, 698 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 863, 772, 783, 698 using Euclid's Algorithm?
Answer: For arbitrary numbers 863, 772, 783, 698 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
