HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 38, 73, 212, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 38, 73, 212, 189 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 38, 73, 212, 189 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 38, 73, 212, 189 is 1.
HCF(38, 73, 212, 189) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 38, 73, 212, 189 is 1.
Step 1: Since 73 > 38, we apply the division lemma to 73 and 38, to get
73 = 38 x 1 + 35
Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 35 and 38, to get
38 = 35 x 1 + 3
Step 3: We consider the new divisor 35 and the new remainder 3, and apply the division lemma to get
35 = 3 x 11 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 38 and 73 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(35,3) = HCF(38,35) = HCF(73,38) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 212 > 1, we apply the division lemma to 212 and 1, to get
212 = 1 x 212 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 212 is 1
Notice that 1 = HCF(212,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get
189 = 1 x 189 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1
Notice that 1 = HCF(189,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 38, 73, 212, 189?
Answer: HCF of 38, 73, 212, 189 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 38, 73, 212, 189 using Euclid's Algorithm?
Answer: For arbitrary numbers 38, 73, 212, 189 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
