HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 535, 620, 495, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 535, 620, 495, 851 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 535, 620, 495, 851 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 535, 620, 495, 851 is 1.
HCF(535, 620, 495, 851) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 535, 620, 495, 851 is 1.
Step 1: Since 620 > 535, we apply the division lemma to 620 and 535, to get
620 = 535 x 1 + 85
Step 2: Since the reminder 535 ≠ 0, we apply division lemma to 85 and 535, to get
535 = 85 x 6 + 25
Step 3: We consider the new divisor 85 and the new remainder 25, and apply the division lemma to get
85 = 25 x 3 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 535 and 620 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(85,25) = HCF(535,85) = HCF(620,535) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 495 > 5, we apply the division lemma to 495 and 5, to get
495 = 5 x 99 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 495 is 5
Notice that 5 = HCF(495,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 851 > 5, we apply the division lemma to 851 and 5, to get
851 = 5 x 170 + 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 851 is 1
Notice that 1 = HCF(5,1) = HCF(851,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 535, 620, 495, 851?
Answer: HCF of 535, 620, 495, 851 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 535, 620, 495, 851 using Euclid's Algorithm?
Answer: For arbitrary numbers 535, 620, 495, 851 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
