HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 521, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 330, 521, 855 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 330, 521, 855 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 330, 521, 855 is 1.
HCF(330, 521, 855) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 330, 521, 855 is 1.
Step 1: Since 521 > 330, we apply the division lemma to 521 and 330, to get
521 = 330 x 1 + 191
Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 191 and 330, to get
330 = 191 x 1 + 139
Step 3: We consider the new divisor 191 and the new remainder 139, and apply the division lemma to get
191 = 139 x 1 + 52
We consider the new divisor 139 and the new remainder 52,and apply the division lemma to get
139 = 52 x 2 + 35
We consider the new divisor 52 and the new remainder 35,and apply the division lemma to get
52 = 35 x 1 + 17
We consider the new divisor 35 and the new remainder 17,and apply the division lemma to get
35 = 17 x 2 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 330 and 521 is 1
Notice that 1 = HCF(17,1) = HCF(35,17) = HCF(52,35) = HCF(139,52) = HCF(191,139) = HCF(330,191) = HCF(521,330) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 855 > 1, we apply the division lemma to 855 and 1, to get
855 = 1 x 855 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 855 is 1
Notice that 1 = HCF(855,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 330, 521, 855?
Answer: HCF of 330, 521, 855 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 330, 521, 855 using Euclid's Algorithm?
Answer: For arbitrary numbers 330, 521, 855 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
