HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 550, 563 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 550, 563 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 868, 550, 563 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 868, 550, 563 is 1.
HCF(868, 550, 563) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 550, 563 is 1.
Step 1: Since 868 > 550, we apply the division lemma to 868 and 550, to get
868 = 550 x 1 + 318
Step 2: Since the reminder 550 ≠ 0, we apply division lemma to 318 and 550, to get
550 = 318 x 1 + 232
Step 3: We consider the new divisor 318 and the new remainder 232, and apply the division lemma to get
318 = 232 x 1 + 86
We consider the new divisor 232 and the new remainder 86,and apply the division lemma to get
232 = 86 x 2 + 60
We consider the new divisor 86 and the new remainder 60,and apply the division lemma to get
86 = 60 x 1 + 26
We consider the new divisor 60 and the new remainder 26,and apply the division lemma to get
60 = 26 x 2 + 8
We consider the new divisor 26 and the new remainder 8,and apply the division lemma to get
26 = 8 x 3 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 868 and 550 is 2
Notice that 2 = HCF(8,2) = HCF(26,8) = HCF(60,26) = HCF(86,60) = HCF(232,86) = HCF(318,232) = HCF(550,318) = HCF(868,550) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 563 > 2, we apply the division lemma to 563 and 2, to get
563 = 2 x 281 + 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 563 is 1
Notice that 1 = HCF(2,1) = HCF(563,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 868, 550, 563?
Answer: HCF of 868, 550, 563 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 868, 550, 563 using Euclid's Algorithm?
Answer: For arbitrary numbers 868, 550, 563 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
