HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 351, 520, 820, 162 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 351, 520, 820, 162 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 351, 520, 820, 162 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 351, 520, 820, 162 is 1.
HCF(351, 520, 820, 162) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 351, 520, 820, 162 is 1.
Step 1: Since 520 > 351, we apply the division lemma to 520 and 351, to get
520 = 351 x 1 + 169
Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 169 and 351, to get
351 = 169 x 2 + 13
Step 3: We consider the new divisor 169 and the new remainder 13, and apply the division lemma to get
169 = 13 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 351 and 520 is 13
Notice that 13 = HCF(169,13) = HCF(351,169) = HCF(520,351) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 820 > 13, we apply the division lemma to 820 and 13, to get
820 = 13 x 63 + 1
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 1 and 13, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 820 is 1
Notice that 1 = HCF(13,1) = HCF(820,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 162 > 1, we apply the division lemma to 162 and 1, to get
162 = 1 x 162 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 162 is 1
Notice that 1 = HCF(162,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 351, 520, 820, 162?
Answer: HCF of 351, 520, 820, 162 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 351, 520, 820, 162 using Euclid's Algorithm?
Answer: For arbitrary numbers 351, 520, 820, 162 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
