HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 656, 669, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 210, 656, 669, 681 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 210, 656, 669, 681 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 210, 656, 669, 681 is 1.
HCF(210, 656, 669, 681) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 210, 656, 669, 681 is 1.
Step 1: Since 656 > 210, we apply the division lemma to 656 and 210, to get
656 = 210 x 3 + 26
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 26 and 210, to get
210 = 26 x 8 + 2
Step 3: We consider the new divisor 26 and the new remainder 2, and apply the division lemma to get
26 = 2 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 210 and 656 is 2
Notice that 2 = HCF(26,2) = HCF(210,26) = HCF(656,210) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 669 > 2, we apply the division lemma to 669 and 2, to get
669 = 2 x 334 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 669 is 1
Notice that 1 = HCF(2,1) = HCF(669,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get
681 = 1 x 681 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1
Notice that 1 = HCF(681,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 210, 656, 669, 681?
Answer: HCF of 210, 656, 669, 681 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 210, 656, 669, 681 using Euclid's Algorithm?
Answer: For arbitrary numbers 210, 656, 669, 681 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
