HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 911, 675, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 911, 675, 655 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, 675, 655 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, 675, 655 is 1.
HCF(911, 675, 655) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 911, 675, 655 is 1.
Step 1: Since 911 > 675, we apply the division lemma to 911 and 675, to get
911 = 675 x 1 + 236
Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 236 and 675, to get
675 = 236 x 2 + 203
Step 3: We consider the new divisor 236 and the new remainder 203, and apply the division lemma to get
236 = 203 x 1 + 33
We consider the new divisor 203 and the new remainder 33,and apply the division lemma to get
203 = 33 x 6 + 5
We consider the new divisor 33 and the new remainder 5,and apply the division lemma to get
33 = 5 x 6 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 911 and 675 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(33,5) = HCF(203,33) = HCF(236,203) = HCF(675,236) = HCF(911,675) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 655 > 1, we apply the division lemma to 655 and 1, to get
655 = 1 x 655 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 655 is 1
Notice that 1 = HCF(655,1) .
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, 675, 655?
Answer: HCF of 911, 675, 655 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 911, 675, 655 using Euclid's Algorithm?
Answer: For arbitrary numbers 911, 675, 655 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
