HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 911, 755, 563 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 911, 755, 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 911, 755, 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 911, 755, 563 is 1.
HCF(911, 755, 563) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 911, 755, 563 is 1.
Step 1: Since 911 > 755, we apply the division lemma to 911 and 755, to get
911 = 755 x 1 + 156
Step 2: Since the reminder 755 ≠ 0, we apply division lemma to 156 and 755, to get
755 = 156 x 4 + 131
Step 3: We consider the new divisor 156 and the new remainder 131, and apply the division lemma to get
156 = 131 x 1 + 25
We consider the new divisor 131 and the new remainder 25,and apply the division lemma to get
131 = 25 x 5 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 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 911 and 755 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(131,25) = HCF(156,131) = HCF(755,156) = HCF(911,755) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 563 > 1, we apply the division lemma to 563 and 1, to get
563 = 1 x 563 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 563 is 1
Notice that 1 = HCF(563,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 911, 755, 563?
Answer: HCF of 911, 755, 563 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 911, 755, 563 using Euclid's Algorithm?
Answer: For arbitrary numbers 911, 755, 563 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
