HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 335, 445, 551, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 335, 445, 551, 65 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 335, 445, 551, 65 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 335, 445, 551, 65 is 1.
HCF(335, 445, 551, 65) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 335, 445, 551, 65 is 1.
Step 1: Since 445 > 335, we apply the division lemma to 445 and 335, to get
445 = 335 x 1 + 110
Step 2: Since the reminder 335 ≠ 0, we apply division lemma to 110 and 335, to get
335 = 110 x 3 + 5
Step 3: We consider the new divisor 110 and the new remainder 5, and apply the division lemma to get
110 = 5 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 335 and 445 is 5
Notice that 5 = HCF(110,5) = HCF(335,110) = HCF(445,335) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 551 > 5, we apply the division lemma to 551 and 5, to get
551 = 5 x 110 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 551 is 1
Notice that 1 = HCF(5,1) = HCF(551,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 1, we apply the division lemma to 65 and 1, to get
65 = 1 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 65 is 1
Notice that 1 = HCF(65,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 335, 445, 551, 65?
Answer: HCF of 335, 445, 551, 65 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 335, 445, 551, 65 using Euclid's Algorithm?
Answer: For arbitrary numbers 335, 445, 551, 65 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
